A ball is thrown vertically with an initial velocity of 20 m/s. Find: A. the maximum height reached by the ball B. the time to reach the maximum height  C. the velocity and time as it returns to the ground

A ball thrown vertically at a velocity of 20 m/s will reach its maximum height of 20 meters in 2 seconds and reach the ground 2 seconds later at a downward velocity of 20 m/s.

Expert Answers

An illustration of the letter 'A' in a speech bubbles

The initial velocity is u = 20 m/s

We can use the following equations of motion to solve this question:

v = u + at

s = ut + 1/2 at^2

v^2 = u^2 + 2as

Here, 'u' is the initial velocity, 'v' is the final velocity, 't' is the time taken, 'a' is the acceleration and 's' is the distance traveled. 

In the case of vertical motion (such as this one), acceleration due to gravity is the only acceleration. For simplicity, let...
