I need to find kinetic energy, but I am given several velocities over 4 seconds. Would it be correct if I use the average velocity to calculate the KE?
question:
A force acts on a 3.0 kg particle-like object in such a way that the position of the object as a function of time is given by x=3.0t-4.0t^2+1.0t^3, with x in meters and t in seconds. Find the work done on the object by the force from t=0 to t= 4.0s.
