Question

Skateboard A Force: 33 N Time: 0.12 s Skateboard B Force: 33 N Time: 0.57 s Skateboard C Force: 33 N Time: 0.78 s Which skateboard has the greatest impulse?

Answer 1

(c)

Step-by-step explanation:

I got it right

Answer 2

The impulse is given by the magnitude of the force times the time interval:

`I= F \Delta t`
We can see that the force F of the 4 skateboard is always the same (33 N), this means that the skateboard with greatest impulse is the one with the largest time interval, so skateboard C).
