What is the net force needed to accelerate a 5 kg object at 3 m/s2? Suppose that in this situation you discovered that there is a 5N force of friction opposing the motion. How large is the applied force acting on the object?

The Force need to accelerate the object is by 3 m/s² is 15 N. Suppose a friction force of 5 N acts on the motion of the object, the force needed to be applied to the object is 20 N

Force:

This can be defined as the product of the mass and the acceleration of a body. The S.I unit of force is kgm/s or Newton(N)

To calculate the force needed to accelerate a mass of 5 kg object at 3 m/s² we use the formula below.

Formula:

F = ma........ equation 1

Where:

F = Net force needed to accelerate the object
m = mass of the object
a = acceleration of the object

From the question,

Given:

m = 5 kg
a = 3 m/s²

Substitute these values into equation 1

F = 5(3)
F = 15 N

Suppose a frictional force of 5 N acts on the motion, The force applied is

F = F'+ma............ Equation 2

Where:

F = Frictional force = 5N

Substitute into equation 2

F = 5(3)+5
F' = 15+5
F = 20 N.

Hence, The Force need to accelerate the object is by 3 m/s² is 15 N. Suppose a friction force of 5 N acts on the motion of the object, the force needed to be applied to the object is 20 N
