What is the impulse on a 3.0 {rm kg} particle that experiences the force described by the graph?

The impulse (Ft) is the area mapped out by the graph. The vertical axis is in standard units but your horizontal axis is in milliseconds (1 ms = 1E-3 sec).

You have a large triangle in the positive region of the graph whose area is :

A₁ = ½BH = ½((8-2)E-3)(2000) ……. (B = breadth; H = height)

A₁ = +6 Ns

You have two smaller triangles, in the negative region, which, when combined make a square whose area is :

A₂ = LB = 2E-3(-500)

A₂ = -1 Ns

The net impulse on the particle is :

Ft = 6 – 1 = 5 Ns
