0.2-kg steel ball is dropped straight down onto a hard, horizontal floor and bounces straight up. The ball's speed just before and just after impact with the floor is 10 m/s. Determine the magnitude of the impulse delivered to the floor by the steel ball.

Answer:
impulsive force is = F × TIME TAKEN
SO , F = m x g ( g = 10 m/s2)
thus the f= 0.2 × 10(kg m/ s2)
f = 2 N
finally. the impulsive force = 2 N × 1sec = 2
so , magnitude is (2)
This ans.may be correct , so please confirm this ans.
