A student holds a ball 1.55 meters above the ground and drops it. Her friend uses a stopwatch and measures a time of 0.57 seconds for the ball to hit the ground. Since the value for g obtained from the data is inaccurate, one of the measurements must have been incorrect. Assuming the time was exactly accurate, from what height was the ball actually dropped?

As you are driving to school one day, you pass a construction site of a new building and you stop to watch for a few minutes. A crane is lifting a batch of bricks on a pallet to an upper floor of the building. Suddenly a brick falls off the rising pallet. You measure the time it takes for the brick to hit the ground and you find it to be 2.5 seconds. The crane has height markings. You saw the brick fell off the pallet at a height of 30.7 meters above the ground. A falling brick can be dangerous, and you wonder how fast the brick was moving when it hit the ground. Since you are taking physics, you quickly calculate the answer.
An engineer is testing how quickly a car accelerates from rest. The velocity V is measured in miles per hour, as a function of time t, in seconds, since the car is at rest. See the table below. What is the slope for the linear function modeling velocity as a function of time, V=, and what would the formula be for the velocity at time 0, V(0) Time (t) Velocity (V) 2.0 28.9 2.5 35.0 3.0 41.1 3.5 47.2
1d. A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v0 = 18.5 m/s. The cliff is h = 20.0 m above a flat, horizontal beach as shown in the figure. Write the equations for the position of the stone with time, using the coordinates in the figure. (Use the following as necessary: t. Let the variable t be measured in seconds. Do not state units in your answer.) x= y=
A student witnesses a flash of lightning and then t = 1.5 s later the student hears the associated clap of thunder.Sound travels at 343 m/s in the air. What distance from the student is the lightning strike, in meters? Light travels at 3.0 × 108 m/s in the air. How long, t1, in seconds did it take the light to reach the student's eyes after the lightning strike?
A boy throws a ball upward in the vertical direction at the base of a hill 40.0 meter high while his friend simultaneously drops another ball from the top of that hill. The two balls collide at a height of 20.0 meter. Find the initial speed (m/s) of the ball that was thrown upward. Express all answers in sig figure And scientific notation.
You are driving home from school steadily at 97 km/hkm/h for 160 kmkm . It then begins to rain and you slow to 61 km/hkm/h instantly. You arrive home after driving 4.5 hours. How far is your hometown from school? answer using two significant figures. What was your average speed? answer using two significant figures.
The acceleration of a particle is a constant. At t=0 the velocity of the particle is (14.91 + 18.4ĵ) m/s. At t = 4.6 s the velocity is 11.4j m/s. (Use the following as necessary: t. Do not include units in your answers.) (a) What is the particle's acceleration (in m/s²)? = î+ 18.4 v(t) = (b) How do the position (in m) and velocity (in m/s) vary with time? Assume the particle is initially at the origin. r(t) = î+ X Î- i) m/s m/s
In an experiment, a shearwater (a seabird) was taken from its nest, flown a distance 5190 kmkm away, and released. It found its way back to its nest 13.5 daysdays after release. If we place the origin in the nest and extend the +x+x-axis to the release point, what was the bird's average velocity for the return flight? Express your answer in meters per second. vav.−xvav.−x = ________________ m/s What was the bird's average velocity for the whole episode, from leaving the nest to returning? Express your answer in meters per second. vav.vav. = __________________ m/s
In my assignment, I was asked to perform a lab experiment. I was to take a provided ball and roll it at a given angle at measured increments - 0.1m-.8m. I measured the time in seconds it took to go from 0 to each point - 0-.1, 0-.2, etc. My lab assignment asked me to perform each step three times. I did this, rolling the ball 3 times from 0-0.1 and calculating the time. I used an app on my phone, slowed down, and went to the closest time interval I could for each test. Naturally, my results for each of the 3 tests for all 8 distances was a bit off, as I would expect given my inexperience and inaccuracy of the tools used to begin with. The lab then asks to chart these values - which I inserted a chart of each trial, the time of each trial, and then calculated the average time ((trial 1 + trial 2 + trial 3)/3). The part I am stuck on is that the next activity it asks me for is: "Calculate the square of the average time for each distance, then create a graph of displacement vs. time…
A tortoise and a hare are competing in a 1200-meter race. The arrogant hare decides to let the tortoise have a 820-meter head start. When the start gun is fired the hare begins running at a constant speed of 8 meters per second and the tortoise begins crawling at a constant speed of 4.5 meters per second. Which of the following formulas expresses the distance between the tortoise and the hare in meters, d, in terms of the number of seconds, t, since the start gun was fired? Od = 820 - 8t Od = 820 + 3.5t Od = 820 - 3.5t Od = 1200 3.5t Od = 1200 - (8t + 4.5t)
The stopping distance for an automobile (after applying the brakes) is approximately F(s) = 1.1s + 0.054s? ft, where s is the speed in mph. Use the Linear Approximation to estimate the change in stopping distance per additional mph when s = 35. (Use decimal notation. Give your answer to two decimal places.) AF = ft Use the Linear Approximation to estimate the change in stopping distance per additional mph when s= 55. (Use decimal notation. Give your answer to two decimal places.)
