A ball is thrown vertically upwards at a speed of 15m/s at the edge of a 20m deep well. The ball is released at a height of 2m above ground level. How high does the ball rise above ground level? If the ball on its downward path falls down the well, how many seconds elapse between releasing the ball and it striking the bottom of the well? Assume that the downward acceleration is 9.81 m/s2 .

At t = 0 s, a ball B1 is thrown vertically upward with a speed of 30 m/s. When B1 is 25 m above ground on the way up, a second ball B2 is thrown vertically upward from the ground with a speed of 40 m/s (Take the magnitude of the acceleration due to gravity g =10m/s2) a) How many seconds after B1 was B2 thrown upward?

A blue ball is thrown upward with an initial speed of 24.1 m/s, from a height of 0.8 meters above the ground. 2.9 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 10.4 m/s from a height of 31.4 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/s2. What is the height of the red...
