Question

A 50. kg remote control car is accelerating on a flat road, and the free body diagram for the car is shown below. If the force of acceleration (to the right) is 800. N and the force of drag (to the left) is 200. N, what is the acceleration of the car?

Answer 1

Answer:

12 m/s²

Step-by-step explanation:

mass of the car = 50 kg

The net force applied to the car is 800 - 200 = 600 N

Form the Newton's second law:

F = m*a

where F is the net force applied to the object, m is the mass of the object, and a is the acceleration of the object.

Then, the acceleration of the car (in m/s²) is:

a = F/m

a = 600/50

a = 12 m/s²
