Aball is thrown vertically upward with a speed of 27.9 m/s from a height of 2.0 m. how long does it take to reach its highest point? the acceleration of gravity is 9.81 m/s 2 . answer in units of how long does the ball take to hit the ground after it reaches its highest point? answer in units of s

2.84403 seconds

2.91483 seconds

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration due to gravity = 9.81 m/s²

It takes 2.84403 seconds to reach the highest point

The ball will travel 39.67431+2 = 41.67431 m while going down to the ground

The ball takes 2.91483 seconds to hit the ground after it reaches its highest point.
