Question

For a moving object, the force acting on the object varies directly with the object's scceleration. When a force of 90 N acts on a certain object, the acceleration of the ebject is 9m^(2)s^(2), If the force is changed to 100N, what will be the acceleration of the object?

Answer 1

The acceleration if the object when force is 100N is 10 meters per seconds squared

How to find the acceleration of the object

Given the direct variation relationship

force , f α acceleration, a

f = ka

k = constant of variation

solving for k

90 = k * 9

k = 90/9

k = 10

when force is 100N

100 = 10 * a

a = 100 / 10

a = 10
