Question

1. What is the mass of the cart with a constant net force of 200N is exerted
to accelerate from rest to a velocity of 40m/s in 10 s.​

Answer 1

Answer:

Force applied on the cart= 200N

Initial velocity = 0m/s

Final velocity = 10m/s

Mass of cart= ?

Acceleration = v-u/t

So A= 40-0/10

A=40/10

A= 4m/s

Force = mass X acceleration

F= ma

M=f/a

M=200/4

M= 50 kg

Mass of the cart = 50 kg
