Aperson throws a ball straight up. he releases the ball at a height of 1.75 m above the ground and with a velocity of 12.0 m/s. ignore the effects of air resistance. (a) how long until the ball reaches its highest point? (b) how high above the ground does the ball go?

a) 1.22 s

b) 9.089 m

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration due to gravity = 9.81 m/s²

Time taken by the ball to reach the highest point is 1.22 seconds

The maximum height the ball will reach above the ground is 1.75+7.339 = 9.089 m
