Question

net force of 30 N is applied to a cart with a mass of 3.0 kg. a. What is the acceleration of the cart? a = m/s2 b. How long will it take the cart to travel 60 m, starting from rest?

Answer 1

The acceleration of the cart is, a = 10 m/s²

The time taken by the cart to reach 60 m, t = 3.46 s

Step-by-step explanation:

Given data,

The net force acting on the cart, F = 30 N

The mass of the cart, m = 3 kg

The acceleration of the cart,

a = F / m

= 30 N / 3 kg

= 10 m/s²

The time taken by the cart to reach 60 m

S = ut + ½ at²

t = √(2S/a) (cart starts from rest)

t = √(2 x 60 /10)

t = 3.46 s

Hence, the time taken by the cart to reach 60 m, t = 3.46 s
