Use the worked example above to help you solve this problem. A ball is thrown from the top of a building with an initial velocity of 21.0 m/s straight upward, at an initial height of 50.7 m above the ground. The ball just misses the edge of the roof on its way down, as shown in the figure. (a) Determine the time needed for the ball to reach its maximum height. s (b) Determine the maximum height. m (c) Determine...

Two throw
A blue ball is thrown upward with an initial speed of 22.2 m/s, from a height of 0.8 meters above the ground. 2.7 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 9.2 m/s from a height of 27.8 meters above the ground. The force of grandly due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s^2. What is the speed of...

When a ball is thrown vertically upward from a reference location, it travels to a maximum height and then changes direction and experiences a fall. Ignoring the air resistance and a number of other tiny influences, the location of the ball (H) and its velocity (V) at time ) can be expressed by the following expressions: Here Vo is the initial upward velocity, g is the earth gravitational acceleration (9.81 m/s)...

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...
