A man has two rocks and throws the first one straight up ten meters high. At the instant the first rock reaches it's highest point, the man throws the second rock upward with the same in initial speed as the first. (a) What was the initial velocity of the first ball? (b) How long will it take the second ball to pass the first? (c) At what height will the two balls pass one another? (d) At that time, which ball is traveling faster? (e) How long was the first ball in the air?

A man throws a ball straight upward with speed 30 m/s from the top of a building that is 75 m high. Ignore air resistance and choose the vertical y-axis to be positive downward with origin at the point of throw (top of the building). Represent the initial velocity and the acceleration vectors in the reference y-axis above. Find the maximum height the ball reaches with respect to the ground. How long does it take the ball to reach the...

A small cannonball is shot straight up from the ground with a launch speed of 26.3 m/s. 2.00 seconds after the cannonball is launched, a ping pong ball is dropped from a height of 36.5 m. Both objects only move in the y-direction. 2a. Where (with respect to the ground) do the cannonball and the ping pong ball pass one another? 2b. How fast and in what direction are each of the balls traveling when they pass one another? 2c....

A rock climber throws a small first aid kit to another climber who is higher up the mountain. The initial velocity of the kit is 13.0 m/s at an angle of 69.0∘∘ above the horizontal. At the instant when the kit is caught, it is traveling horizontally, so its vertical speed is zero. What is the vertical height difference between the two climbers?
A person standing at the edge of a cliff throws one ball straight up and another...
A person standing at the edge of a cliff throws one ball straight up and another ball straight down at the same initial speed. Neglecting air resistance, the ball to hit the ground below the cliff with the greater speed is the one initially thrown 1. Upward 2.Downward 3.Neither—they both hit at the same speed I know the answer is 3. But I dont know how to prove it. Plz help with it.

At t = 0, Ball 1 is dropped from the top of a 19 mm-high building. At the same instant Ball 2 is thrown straight up from the base of the building with an initial velocity of +12 m/sm/s. Assume that Ball 1 starts from rest and that air friction can be ignored. At what height will the two balls pass each other? What is the velocity of each ball at the moment they are at the same height?  Express...
