Question

A force of 10 N acts on a body of mass 0.5 kg for 0.25s starting from rest. What is its impulse?

Easy

A

0.25 N-s
B

2.5 N-s
C

0.5 N-s
D

0.75 N-s

Solution

$Given, F = 10 N, v_{i} = 0, m = 0.5 kg and Δ t = 0.25 s$
$As impulse, I = p_{f} - p_{i}$
Also, $I = F \cdot Δ t = 10 \times 0.25 = 2.5 N - s$
