Q1. A 13.00 g bullet travelling 224 m/s penetrates a 2.0 kg block of wood and emerges cleanly at 160 m/s. If the block is stationary on the frictionless surface when hit, how fast does it move after the bullet emerges?
Q2. A hiker's trip consists of three segments. Path A is 7.00 km long heading 60.00 degrees north of east. Path B is 6.00 km long in the direction due east. Path C is 5.00 km long heading 315 degrees counter clockwise from east. Graphically add hiker's displacements in the order A, B, C and give the direction of the displacement.
