At time t0 = 0 seconds a rock is dropped from rest (rock #1). One second later, a second rock (rock #2) is dropped from the same height --- also from rest. What are their separation distances ΔX and the differences in their velocities ΔV at t = 1 sec,
2 sec, 3 sec, and 4 sec?

A rock is dropped from a height of 64 ft. It is determined that its height (in feet) above ground t seconds later (for 0≤t≤2) is given by s(t)=−16t2+64. Find the average velocity of the rock over each of the given time intervals. Use this information to guess the instantaneous velocity of the rock at time t=0.5. 1. [0.49, 0.5] 2. [0.5, 0.51] Can you please show every step to solving this problem?

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...

A model of rocket weighing 0.2 lbs is initially at rest at time t = 0 when launched vertically upwards using a propulsive force of 2 lbs. This propulsive force is applied from 0 <t ≤ 1 sec. When t> 1 sec, the propulsive force stops acting. By neglecting the resistance of the air and assuming that the mass of the rocket remains constant, determine a) The time required for the rocket to reach its maximum height. b) The maximum...

2) A ball is dropped from rest at the top of a high cliff. It takes 10.00 seconds for the ball to reach the ground below. Find: a) the height of the cliff, b) the velocity of the ball hitting the ground below, c) the time it takes for the ball to fall half of the cliff's height, and d) the velocity at this halfway point. (Remember acceleration due to gravity is -9.800 m/s^2).

qt9.2 A stone is dropped at t = 0. A second stone, with 5 times the mass of the first, is dropped from the same point at t = 170 ms. (a) How far below the release point is the center of mass of the two stones at t = 430 ms? (Neither stone has yet reached the ground.) (b) How fast is the center of mass of the two-stone system moving at that time?
