Atennis ball is shot vertically upward in an evacuated chamber inside a tower with an initial speed of 20.0 m/s at time t = 0 s. approximately how long does it take the tennis ball to reach its maximum height?

Time taken to reach its maximum height is 2.04 seconds.

Explanation:

It is given that, a tennis ball is shot vertically upward in an evacuated chamber inside a tower with an initial speed of 20.0 m/s at time t = 0 s.

At maximum height, its final velocity v = 0

Let t is the time taken by the tennis ball to reach its maximum height. We know that for a freely falling object, the value of acceleration is -g or -9.8 m/s².

Using first equation of motion as :

t = 2.04 seconds

Therefore, this is the required solution.
