A boxer throws a punch with a force of 1,400 N that lasts 0.02 s. What is the impulse of this punch? (1 point) Responses 7,000 kg⋅m/s 7,000 kilograms times meters per second 70,000 kg⋅m/s 70,000 kilograms times meters per second 28 kg⋅m/s 28 kilograms times meters per second 280 kg⋅m/s
To calculate impulse, we can use the formula: impulse = force × time.
Given that the force is 1,400 N and the time is 0.02 s, we can calculate the impulse as follows:
impulse = 1,400 N × 0.02 s
impulse = 28 N·s
Therefore, the impulse of this punch is 28 N·s, which can also be written as 28 kg·m/s.
