Question

1. what impulse will give a 2.0 kg mass at rest a momentum change of +50 kg m/sec? (1 point)

50 ns
25 ns
0.04 ns
0 ns
dont be silly, its none of these!

Explanation:

Step1: Recall impulse - momentum theorem

The impulse - momentum theorem states that the impulse \(J\) is equal to the change in momentum \(\Delta p\), i.e., \(J=\Delta p\).

Step2: Identify given values

We are given that \(\Delta p = + 50\ kg\cdot m/s\).

Answer:

A. \(50\ Ns\)
