What is the value of the impulse obtained from the graph?

C) 9 kilogram meters/second

Explanation:

The impulse is defined as the integral of the force over the time:

in a force-time graph, the impulse corresponds to the area under the curve. Therefore, in this case we can calculate the impulse by finding the area of the triangle.

The base is 3 s, while the height is 6 N, therefore the area (and the impulse) is

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
