Question

The force involved in a collision is 1.0 × 102 newtons. The duration of the impact is 1.0 × 10-4 seconds. What is the value of the change in momentum?

Answer 1

d 1.0 × 10-2 kilogram meters/second

Answer 2

The correct answer to the question is :
`10^(-2)\ N.s`

Step-by-step explanation:

As per the question, the force involved in the collision F =
`1.0* 10^2\ N.`.

The duration of impact is given as t =
`1.0* 10^(-4)\ s`.

We are asked to calculate the change in momentum.

We know that the change in momentum is equal to the impulse of a body .

The impulse of a body is defined as the product of force with time.

Hence, impulse = force × time

= F × t

=
`1.0* 10^2\ N* 1.0* 10^(-4)\ s`

=
`10^(-2)\ N.s` [ans]

Hence, the change in momentum is
`10^(-2)\ N.s`
