Question

If a 5.5 kg object experiences 15 N of force for .15 seconds what is the speed change

Answer 1

The speed change : Δv = 0.41 m/s

Further explanation

Given

mass = 5.5 kg

Force = 15 N

time = 0.15 s

Required

the speed change

Solution

Newton 2nd's law

Impulse and momentum

F = m.a

F = m . Δv/t

F.t = m.Δv

Input the value :

15 N x 0.15 s = 5.5 kg x Δv

Δv = 0.41 m/s
