Chapter 04, Problem 101 In the figure, a ball is shot directly upward from the ground with an initial speed of vo 9.20 m/s. Simultaneously, a construction elevator cab begins to move upward from the ground with a constant speed of vc = 2.80 m/s, what maximum height does the ball reach relative to (a) the ground and (b) the cab floor? At what rate does the speed of the ball change relative to (c) the ground and (d) the...

Free-fall notion 1. A ball is thrown vertically upward at an initial speed of 49 m/s. Assume that the ball leaves the hand when it is 15 m above the ground (about the height of Kirkbride), and that the effects of air resistance can be ignored. Choose your landmark to be the ground; then at t -0, yo- +15 m, Vyo +49 m/s a. 5 pts) How fast is the launch speed in mph? Do you think this is a...

A 0.36-kg ball is thrown vertically upward with an initial speed of 12.5 m/s. What is the potential energy of the ball when it has travelled two-thirds of the distance to its maximum height? (Use the launch point to be the zero reference point of measurements of the heights)
A blue ball is thrown upward with an initial speed of 23.9 m/s, from a height...
A blue ball is thrown upward with an initial speed of 23.9 m/s, from a height of 0.5 meters above the ground. 2.9 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 7.5 m/s from a height of 31.5 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s^2. How long after the blue ball is...
