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/Δt
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?
