Question

You wish to push a cart across a frictionless surface, so you apply a force of 50 N force for a

period of 50. 0 seconds. As a result the cart goes from rest to a velocity of 2. 3 m/s. What is the

mass? Hint (must find acceleration first. )

Answer 1

Answer: 1087 kg

Step-by-step explanation:

F = ma, so m = F/a

find a = change in velocity / change in time

a = (2.3 m/s - 0 m/s) / 50 s = 0.046 m/s2

now find m

m = F/a = 50N / 0.046 m/s2 = 1087 kg
