Question

1. calculate the change in momentum using the graph above. clear all 2000 ns 2400 ns 40 ns 4000 ns

Explanation:

Step1: Recall the formula for change in momentum

The change in momentum ($\Delta p$) is equal to the impulse ($J$), and impulse is the area under the force - time ($F - t$) graph.

Step2: Calculate the area of the triangle

The formula for the area of a triangle is $A=\frac{1}{2}\times base\times height$.
From the graph, the base of the triangle (time interval) is $40\ s$ and the height (maximum force) is $100\ N$.
