What is the rate of change of momentum when a constant 4N force acts on a mass of 2Kg for 2 seconds ?
change in momentum = impulse produced (on the 2Kg mass) by the force
The Attempt at a Solution
i used the above equation to first find the impule
as I = δP
hence δP/δt = 8/2 = 4 Kg m s^-2
In simple terms as force = rate of change of momentum thus 4N shud be the answer...
but my teacher rejected the answer 4 but instead said that it would be 8
