Question

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 28 N acts on a certain object, the acceleration

of the object is 4 m/s^2. If the acceleration of the object becomes 5 m/s², what is the force?

Answer 1

35 N

Step-by-step explanation:

F = ma (Newton's 2nd Law)

Find mass of the object:

m = F/a = (28 N) / (4 m/s²) = 7.0 kg

Find Force when a = 5 m/s²:

F = (7.0 kg)(5 m/s²) = 35 N
