Question

Calculate the impulse using this force-time graph of a small cart being pushed.

0.060 kg • m/s


0.140 kg • m/s


0.100 kg • m/s


0.080 kg • m/s

Answer 1

Impulse is the area under the force vs time graph, or FΔt. 2N · 0.040 s = 0.080 Ns, or kgm/s.

Answer 2

Answer: The impulse for the following graph is 0.080 kg.m/s

Step-by-step explanation:

To calculate the impulse we use the formula:

`Impulse=F\Delta T`

Where, F = Force

T = Time

For the following Force-time graph, the impulse will be equal to the area of the rectangle.

Area of the rectangle = l × b

Here, l = length of the rectangle = (2 - 0)N = 2N

b = Breadth of the rectangle = (0.07 - 0.03)s = 0.04s

Putting values in above equation, we get:

Impulse = 2 × 0.04 = 0.08 kg.m/s

Hence, impulse for the following graph is 0.080 kg.m/s
