Question

An 860-kg Smart Car has an acceleration of 0.75 ms-2. What is the work done by the net force acting on the car if it travels 45 meters

Answer 1

29025 J

Step-by-step explanation:

In physics work is the product of force and distance but according to Newton's law, force is the product of mass and acceleration.

Hence;

F =ma

W=Fs

Therefore;

W= mas

From the question;

m= 860 kg

a= 0.75 ms-2

s= 45 meters

W= 860 * 0.75 * 45

W = 29025 J
