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
<h3>Force:</h3>
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:
Substitute these values into equation 1
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
