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?

0.26 newton seconds
0.58 newton seconds
1.82 newton seconds
2.20 newton seconds

Answer 1

other guy got it right

Step-by-step explanation:

Answer 2

Correct Answer: 0.26 Newton Seconds

Impulse is defined as the product of Force applied and the time taken.

Force = F = 520 Newtons
Time = t =
`5*10^(-4)` seconds.

So,

Impulse = Ft =
`520*5*10^(-4)=0.26` Ns

Therefore the value of impulse would be 0.26 Newton seconds.
