Question

A 2,500-kg car hits a fence with a force of 400 N, and the collision takes one

second. What is the magnitude of its impulse?

A. 6.25 kg-m/s
B. 400 kg-m/s
C. 1,000,000 kg-m/s
D. 10,000 kg-m/s


Help plz

Answer 1

B. 400 kg-m/s

Answer 2

Answer:B. 400 kg-m/s

Explanation: To calculate impulse(I)

I = Force×time

where;

Force=400N

Time=1 seconds

I=400N×1 sec

I=400kg-m/s

Where,force =kgm/s^2

And time =seconds

Therefore the impulse unit =kgm/s
