Question

A ball of mass 'm' moving horizontally with velocity 'u' along positive x direction , strikes a wall for a very small time interval 't' and rebounds back with same speed along the same path. The ball experiences force which is equal to _____________ in ________________direction​

Answer 1

Answer:

mass = m

initial velocity = u (constant)

time = t

therefore, acceleration = u/t ( constant velocity)

force = m×a

= um/t N

hence force on object = um/t Newton in 'x' direction which is perpendicular to the wall.
