    What is the net force acting on an object at t=2 with a given momentum equation?

    Homework Statement An objects momentum is given by the following equation p(t) = 4t3-6t+1. What net force is acting on the objects at t=2?Homework Equations P=m*v F=Δp/ΔtThe Attempt at a Solution So, I was thinking if F=m*a I can change a and get F=m*(Δv/Δt) and knowing what I know about p...
