Question

For a moving object, the force acting on the object varles directly with the object's acceleration. When a force of 45 N acts on a certain object, the acceleration

of the object is 5 m/s?. If the force is changed to 63 N, what will be the acceleration of the object?

Answer 1

acceleration,A = 7

Explanation:

F = kA

First expression: 45 = 5k, k = 9

therefore, when F = 63, A = 63/9 = 7
