- A coin is dropped from a height of 960 feet. The height, s (measured in feet), at time, t (measured in seconds), is given by s=-16t2+960 a) find the average velocity on the interval [1.5, 3.5] b) How long does it take for the coin to hit the ground? c) Find the velocity of the coin when it hit the groundQuantitatively draw the corresponding velocity-vs-time graph(include numerical values). Be sure to label axes, ticks, and include proper units.Hello, I am needing help with the position-time graph on the top right (the one with the negative parabolic shape). A tutor and I came up with the following velocity-time and acceleration-time graphs, but I wanted to double check if these are correct, and some explanation as to why. Thank you!
- Sketch a velocity vs time graph of an object that is released from rest and then reaches termainal velocity. Be sure to label each coordinate axis.Given the velocity vs time plot below, what is the acceleration? (Note the horizontal axis is time in s and the vertical axis velocity in m/s).A meter stick is held vertically above your hand, with the lower end between your thumb and first finger. On seeing the meter stick released, you grab it with these two fingers. You can calculate your reaction time from the distance the meter stick falls and read directly from the point where your fingers grabbed it. Derive a relationship for your reaction time in terms of this measured distance, d. If the measured distance is 15 cm, what is the reaction time (in seconds)?
- I wonder if you can't assist me with this problem. I see that we're being asked to find V_o, but in order to solve, we need to calculate the time and the acceleration. We have the means to solve for acceleration using the second set of data values, then plug that value in to find time. But i'm a bit lost after that. Attached are photts of the question and my work.Which of the dot diagrams below represents the motion of an object whose velocity and acceleration point in opposite directions? Please note the time designations to figure out the direction of motion. There may be more than one answer.Which of the following is the correct velocity-vs-time graph?
- If you were to drop a large log over the edge of the Grand Canyon and it took 6.26 seconds to hit the ground, calculate the velocity of the log at impact in m/s. 2A paratrooper falls with the velocity 4 m/s. During his motion, western wind blows with velocity of 3 m/s. The factual velocity of the paratrooper with respect to the ground is: Give the answer in m/s side note: How would I know what formula to use for this problem and what formula is needed for this problem?Problem 1: An object is launched off the top of a 45-m tall building with velocity of 70.9 m/s in the horizontal direction (no angle with respect to the horizontal). Pai. (a) In the space below, explain how you would find the time that the object is in the air. (Type the equation(s) you would use and the variable(s) you would solve for. Describe any other important steps. Do not show calculations or the numeric answer.)
