Question

A karate expert breaks a stack of bricks with his bare hand. If the force applied is 520 newtons and the impact time is 5.0 × 10-4 seconds, what is the value of impulse?

Answer 1

This question could be solved with this formula:
F . ΔT
From which F= The amount of force applied
and ΔT = the impact time ins seconds

So, the Value of impulse would be:
520 N x 5. x 10^-4 seconds

= 0.052 N x 5

= 0.26 Newton Seconds
