Impulse can be calculated using the formula:
\[ \text{Impulse} = \text{Force} \times \text{Time} \]
In this case, the force of the punch is \(1,500 , \text{N}\) and the time duration is \(0.03 , \text{s}\).
Calculating the impulse:
\[ \text{Impulse} = 1,500 , \text{N} \times 0.03 , \text{s} = 45 , \text{Ns} \text{ (or kg.m/s)} \]
Thus, the impulse of the punch is 45 kg.m/s.
The correct response is:
45 kg.m/s
