Question

The magnitude of force acting on a body varies with time as shown in the figure. The magnitude of total impulse of the force on the body from t = 0 to t = 16 μs is-, 6 × 10 - 3 N s, 5 . 8 × 10 - 3 N s, 8 . 4 × 10 - 3 N s, 7 . 6 × 10 - 3 N s

Impulse = ∫ F d t = area under curve Area = 200 × 4 + 1 2 × 2 × 200 + 800 + 1 2 × 10 × 800 × 1 0 - 6 Area = 800 + 1000 + 4000 × 1 0 - 6 Area = 5800 × 1 0 - 6 = 5.8 × 1 0 - 3 Ns
