Question

A force of 19 newtons is applied on a cart of 2 kilograms, and it experiences a frictional force of 1.7 newtons. What is the acceleration of the cart

Answer 1

Answer:

8.6 meters/second^2

Explanation:

Net force = 19 N - 1.7 N = 17.3 N

F = ma

17.3 N = 2 kg * a

a = 17.3 N / 2 kg  (N= kg*m/s^2)

a = 8.6 m/s^2

Answer 2

Frictional force always opposes applied force, so the net force on the cart would have to be 19N - 1.7N. The acceleration can then be solved by using the relation: F = ma. This is shown below:

Net force = 19 - 1.7 = 17.3 N

Acceleration = Force / mass
Acceleration = 17.3 / 2
Acceleration = 8.65 N/m
