The power required to accelerate the object at
Explanation:
Power is also defined as the product of force and velocity.
Now we have to find out force value as velocity value is already given.
This case is taken as Motion of block on a rough fixed horizontal surface.
Here the force is defined
Now substitute this force in above power definition, we get
By substituting the given numerical values
