A force of 10N act on a body of mass 5Kg than rate of change of momentum is?

1 answer

The rate of change of momentum is given by the formula:

force = rate of change of momentum / time

We are given:

force = 10N
mass = 5Kg

Using the formula for momentum:

momentum = mass x velocity

We can rearrange the formula to find the velocity:

velocity = momentum / mass

Since the initial momentum is zero, the final momentum is just the product of the mass and velocity after the application of force:

final momentum = mass x velocity

Using these equations, we can find the rate of change of momentum as follows:

force = rate of change of momentum / time
10N = (mass x final velocity - 0) / time
10N = (5Kg x velocity - 0) / time
10N x time = 5Kg x velocity

Dividing both sides by 5Kg:

2m/s = velocity

Substituting this into the equation for final momentum:

final momentum = mass x velocity
final momentum = 5Kg x 2m/s
final momentum = 10Kg m/s

Therefore, the rate of change of momentum is:

rate of change of momentum = final momentum / time
rate of change of momentum = 10Kg m/s / time
