A man carries 40 tiles from the ground to the roof of a house. each tile has a mass of 1.5 kg . the roof of the house is 20 m above the ground. how much work does the man do against graviy on the tiles in carrying the roof? ​

The ball will reach an height of 31.88 meters before coming to a stop.

Explanation:

we know that by equation of motion

where v is the final velocity of the ball , u is the initial velocity of the ball , a is acceleration due to gravity and s is the distance traveled by the ball.

a = -9.8

and u = 25 m/s

and v = 0

therefore s =

so s = 31.88 meters
