A boxer throws a punch with a force of 1800N that lasts 0.02s. What is the impulse of this punch?(

The impulse of a punch is equal to the product of the force applied and the time interval over which it is applied.

Impulse = Force x Time

Impulse = 1800N x 0.02s
Impulse = 36 N·s

Therefore, the impulse of this punch is 36 N·s.
