Question

A picnic bench experiences 10 kg m/s of impulse when pushed for 2.5 seconds. How many Newtons of force was it pushed with?

Answer 1

The force applied to the picnic bench to achieve an impulse of 10 kg m/s over 2.5 seconds was 4 Newtons.

Step-by-step explanation:

To calculate the force that was applied to the picnic bench, we need to use the formula that relates impulse, force, and time.

Impulse is equal to the change in momentum, and it is also the product of the force (F) applied and the time interval (t) over which the force is applied. The formula is given by Impulse = F * t.

Given the impulse is 10 kg m/s and the time is 2.5 seconds, we rearrange the formula to solve for the force:

F = Impulse / t

F = 10 kg m/s / 2.5 s = 4 N

Therefore, the force applied to the picnic bench was 4 Newtons.
