Q9

Two blocks collide. Immediately before the collision, the 2kg block A slides right at 3m/s, and the 4kg block B slides left at 5m/s. Immediately after the collision, block A slides left at 6m/s. A little glue is placed on the sides of the blocks so that they remain glued together after the collision. Determine the velocity modulus and orientation of the blocks immediately after the collision, and the percentage of kinetic energy lost during the collision. Sketch the situation.

A vertical circular cross-sectional jet of air strikes a conical deflector as shown in Figure H. A vertical anchoring force of 0.1N is required to hold the deflector in place. Determine the mass [kg] of the deflector. The magnitude of velocity of the air remains constant. Neglect gravity of air as well as pressure differences.
