Afancart of mass 0.8 kg initially has a velocity of < 0.9, 0, 0 > m/s. then the fan is turned on, and the air exerts a constant force of < -0.3, 0, 0 > n on the cart for 1.5 seconds. what is the change in momentum of the fancart over this 1.5 second interval? = < , 0, 0 > kg

<-0.45, 0, 0> kgm/s

Explanation:

The change in momentum would equal to the impulse generated by force F = <-0.3, 0, 0> over time duration of Δt = 1.5 second. The impulse is defined as the product of force F and the duration Δt

So the change in momentum is <-0.45, 0, 0> kgm/s
