2. (a) (K) What is the acceleration of the system shown below if both blocks have a mass of 5.0 kg, and the coefficient of kinetic friction is 0.11? [/4] (b) (K) Determine the tension in the rope. [ /2] 3. (T) A pilot of mass 65 kg in a jet aircraft makes a complete vertical circle in mid-air. The vertical circle has a radius of 1.70 km at a constant speed of 215 m/s. Determine the force of the seat on the pilot at (a) the bottom of the loop and (b) the top of the loop. (Note that at the top of the loop, the aircraft is upside down.)
