What is the value of the impulse obtained from the graph? a. 3 kilogram meters/second b. 8 kilogram meters/second c. 9 kilogram meters/second d. 10 kilogram meters/second e. 7 kilogram meters/second

Answer

C. 9 kilogram meters/second

Explanation

Inpulse of a force = force(N) × time(s)

Since the force is not constant for the given time, Impulse of force will be will the area under the graph of force against time.

The area of the graph shown = 1/2 × 6 × 3

                                                  = 3 × 3

                                                  = 9

Answer = C. 9 kilogram meters/second
