Question

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 35 N acts on a certain object, the acceleration of the object is 7m/s . If the force is changed to 20 N, what will be the acceleration of the object?

Answer 1

4 m/s

Explanation:

This is just a simple ratio question

35N=7M/s

20=Xm/s

We see that 7 is 1/5 of 35

20 is 4/7 of 35

4/7 of 7 is 4
