Compute all parts of following problem:
Problem: The position of a particle of mass m = 2kg is given by r=i(3t2-4t)+j(t3-8t2+10).
Part A: Find the magnitude and direction of the force acting on the particle at time t = 5seconds?
Part B: Calculate the angle between the force vector and the velocity vector at time t=2?
I need help to find the magnitude and direction of the force acting on the particle.
