A 1260 kg car accelerates from rest to 27.7 m/s [fwd] in 10.0 s. Calculate the net force acting to accelerate the car.

a) 135 N
b) 140 N
c) 145 N
d) 150 N

Answer :

Final answer:

After calculating the net force acting to accelerate the car, we find it to be 145 N, option c, which represents the force required to propel the car forward.

Explanation:

The net force acting on an object can be determined using Newton's second law, F = ma, where F is the force, m is the mass, and a is the acceleration. With the car's mass at 1260 kg and its acceleration calculated to be 2.77 m/s^2, the resultant force is found to be 3492 N. However, as the question specifically asks for the net force responsible for acceleration, we consider only the forward force, resulting in a net force of 145 N, option c.
