Question

a car has a mass of 975kg. by pushing on the car Evan increase its speed from 0.5 m/s to 3 m/s. what impulse did evan apply to the car

Answer 1

From newton's second law you can find that, for a constant force applied for a time t
Ft = change in momentum
and Ft is what we call the impulse.

Answer 2

ok so how do i solve it im lost

Answer 3

well you need to work out the change in momentum of the car, and that tells you the impulse that was applied to it

Answer 4

whatttttttttttttttttttttttttttttttttttt

Answer 5

: ( so you don't know how momentum is defined ?

Answer 6

no

Answer 7

mass multiplied by velocity is momentum
