A 20 kg mass starting from rest has position dependent force acting on it. The force is:
F(x) = 1000 x^2 + 25000 x – 330, with force in newtons and position in meters. The mass moves from x = 0 to x = 70 cm.

Find the work done on the mass by this force. Find the final velocity of the mass.
Find the average power produced by the force over a time period of 3 seconds.
