An air bag applies a force of 6100 N to bring about a change in momentum of 5250 kg m/s. How much time did it act over?

1 answer

We can use the formula for impulse:

Impulse = Force * Time

We are given the force as 6100 N and the change in momentum as 5250 kg m/s.

Thus,

Impulse = 6100 N * Time
5250 kg m/s = 6100 N * Time

To find the time, we can rearrange the equation:

Time = (5250 kg m/s) / (6100 N)

Time ≈ 0.861 seconds
