Question

a player hits a football the ball moves around a curved path and Falls back to the ground at a distance of 40 m from the player what is the work done by the force of gravity on the ball​

Answer 1

Answer:

gravitisional force is used by ground

Answer 2

Answer:

0

Explanation:

Work done by the gravity on the foot ball is zero as the gravity is acting downwards but the displacement is in the perpendicular direction.

we knowW=F.D.cosθ;θ=90

0

so hence,work done W=0
