1. The problem statement, all variables and given/known data 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? 2. Relevant equations P=m*v F=Δp/Δt 3. The 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, I change it to F=Δp/Δt So then I was just solving the equation for t=2 and t=0 to get (21-1)/(2-0) = 10 Is that correct or am I totally thinking about this wrong?
