Question

1. how much force would be needed to cause a 17 kg·m/s change in the momentum of an object, if the force acted for 5 seconds?

a. 3.4 n
b. 12 n
c. 22 n
d. 85 n

Explanation:

Step1: Recall the formula for force

Force \( F=\frac{\Delta p}{\Delta t} \), where \( \Delta p\) is the change in momentum and \( \Delta t\) is the time interval.

Step2: Substitute the given values

Given \( \Delta p = 17\space kg\cdot m/s\) and \( \Delta t=5\space s\). Then \( F=\frac{17}{5}\).

Step3: Calculate the value of \( F\)

\( F = 3.4\space N\)

Answer:

A. \( 3.4\space N\)
