Question

How much force is needed to accelerate an object of mass 90 kg at a rate of 1.2 m/s2? 0.013 N 75 N 108 N 1080 N

Answer 1

F = m*a

F = 90*1,2

F = 108 N

Answer 2

Force needed to accelerate an object is 108 N. The correct option is third.

What is Net force?

When two or more forces are acting on the system of objects, then the to attain equilibrium, net force must be zero.

From the Newton's second law of motion, force is given by

F = ma

where, m is the mass of the object and a is the acceleration

Given

Plug the values, we get

F = 90 x1.2

F = 108 N

So, the force needed is 108 N.

Thus, the correct option is third.
