1. What average force is exerted on a 25 g egg by a bed sheet if the egg hits the sheet at 4 m/s and takes 0.2 s to stop?

F = -0.5 N

Explanation:

Given that,

Mass of an egg, m = 25 g = 0.025 kg

Initial speed, u = 4 m/s

Final speed, v = 0 (it stops)

Time, t = 0.2 s

We need to find the average force exerted on the egg. The force is given by :

F = ma

So, the average force exerted on the egg is (-0.5 N).
