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?

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

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

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

a and b sometimes have a positive value
