Q1. An aluminium block of mass m1= 3 kg and a copper block of mass m2= 8 kg are connected by a light string over a frictionless pulley. They are on a steel surface as shown below, where theta= 40. The coefficient of static friction of copper on steel is .58. When they are released from rest, will they start to move? If the blocks move find out the magnitude of their acceleration. If the blocks move determine the magnitude of the tension in the string. If the blocks do not move determine the sum of magnitude of the forces of friction acting on the blocks. Show all the work.

Q2. On level ground a shell is fired with an initial velocity of 88.8 at 53.8 above the horizontal and feels no appreciable air resistance.
