Q1. An explosive charge imparts a velocity of 10,350 feet per second to a mortar as it exits the muzzle of mortar. If the mortar is elevated at 80 degrees what are the horizontal and vertical velocities on the mortar shell?

Q2. Block A is on an incline that makes an angle of 30^o above the horizontal. It is attached via a cord over a frictionless pulley at the top of the incline to a second block, B that is hanging vertical above the ground. The mass of A is 2.6 kg and the mass of B is 2.2 kg. The coefficient of friction between A and the incline is μk = 0.180. The picture would be similar to that for problem 6.37 on page 180. A) Illustrate free-body diagrams for all the forces acting on bodies A and B. B) Write down the net force equations for both blocks and solve for the acceleration of block B.
