Impulse — Large ForceHardQuestion 30520

Question

In a collision, the contact force varies from 0 to 10000 N in 0.001 s (linearly). The impulse is:
  1. A
    10 N·s
  2. B
    5 N·s
    Correct
  3. C
    0.5 N·s
  4. D
    10000 N·s

Correct answer

5 N·s

Explanation

Impulse = area under F-t graph = ½×base×height = ½×0.001×10000 = 5 N·s.
