Question

A) sometimes accelerate B) always move off at a constant speed C) always accelerate at a constant rate D) accelerate whenever the force exceeds the weight of the body E) remain at rest Secuon ipoints each. Circie the correct response. 1) If a nonzero constant net horizontal force acts on a body initially at rest on a orizontal surface the body will a) sometimes accelerate. b) always move off at a constant speed. always accelerate at a constant rate. d) accelerate whenever the force exceeds the weight of the body. remain at rest.

Explanation / Answer

a is the correct option

Sometimes accelerate .

If the applied constant force is greater than static friction force the object will move.

If the applied constant force is less than static friction force the object will not move.

We are not sure about the applied force it may be greater than the static frictional force or it may be less than static friction force. So we can say that sometimes accelerates.
