Standing on the edge of a cliff that is 800 m above the ground. You take a stone and throw it straight up imparting the stone with an initial velocity of 8.30 m/s (UP). What is the velocity of the stone 10 seconds after you throw it up? Air resistance doesn't have an effect
A ball is dropped from the top of a building 150m high, at the same instant
another is thrown upward from the ground. The balls pass each other at a point
60 m above the ground. What was the initial velocity of the second ball? Draw
the figure properly. No figure no point.
Amir starts riding his bike up a 195-m-long slope at a speed of 5 m/s, decelerating at -0.14 m/s2 as he goes up. At the same instant, Becky starts down from the top at a speed of -2 m/s, accelerating at -0.48 m/s2 as she goes down. How far has Amir ridden when they pass each other?

- A rock is tossed straight up with a speed of 17m/s. When it returns, it falls into a hole 10m deep. What is the rocks velovity as it hits the bottom of the hole? How long is the rock in the air, from the instant it is released until it hits the bottom of the hole?arrow_forwardA student standing on the ground throws a ball straight up. The ball leaves the student’s hand with a speed of 15 m/s when the hand is 2.0 m above the ground. How long is the ball in the air before it hits the ground? (The student moves her hand out of the way.)arrow_forwardSmoky, the cat, is relaxing on the arm of a couch, 1m above the ground, when he is startled by something and jumps straight up in the air with an initial speed of 4 m/s. Coming down he missed the couch and lands on the ground. ( ignore air resistance) time to reach max height is .408 s max height is 1.816 m What is smoky's velocity just before he hits the ground?

- Two children are playing on a 151-m-tall bridge. One child drops a rock (initial velocity zero) at t = 0. The other waits 1.1 s and then throws a rock downward with an initial speed Vo. If the two rocks hit the ground at the same time, what is vo? m/sarrow_forwardA model rocket is launched and accelerates upward at 20m/ s2 for 3 seconds before the jet shuts off. It continues to rise until gravity eventually brings it back down. How long its takes the rocket in the air?arrow_forwardAn object is thrown into the air with initial velocity v = 5m/s. After being released it is only subject to the acceleration due to gravity a = -9.81m/s2 slowing it down. It will, as you know, eventually stop moving upwards and then begin coming back down towards the person who threw it. At the top most point of its journey, it will be at rest for a brief instant in time. How long from when it was initially thrown until it reaches its highest point in the air? Please write it out. I can't fully follow along if the solution is typed outarrow_forward
- A billiard ball was set in motion on a counter by your mischievous little cousin who wanted the ball to hit your foot. To avoid your attention he set the ball in motion with a slow speed of 1.0 m/s (how did he know this unit?!) from a counter that is 1.1 m tall. Fortunately he missed. How long did it take to hit the floor?arrow_forwardA man gets mad at his messed up computer and tosses it out of a 30 m high window. What is the velocity of the computer as it hits the ground? Another man hears the yells from the ground and looks up . How much time does he have to avoid the falling computer?arrow_forwardNatalia throws a ball straight up. The ball leaves the her hand with a speed of 12.0 m/s when the hand is 1.70 m above the ground. How long is the ball in the air before it hits the ground?

What is the particle's velocity when t=6 s, and what is its position when t=11 s? If a particle has an initial velocity of v, = 12 ft/s to the right, at so = 0, determine its position when t = 10 s, if a = 2 ft/s² to the left.arrow_forwardI throw a ball up into the air and it lands back down in my hand (at the same height it was thrown from) after exactly one second How high above where it was thrown from did the ball reach?
