A block weighing 60.0 n rests on a plane inclined at, Ask an Expert

Academics

Q1. A 12.0 g bullet travelling 221 m/s penetrates a 2.00 kg block of wood and emerges going 126 m/s. If the block is stationary on the frictionless surface when hit, how fast does it move after the bullet emerges?

Q2. A block weighing 60.0 N rests on a plane inclined at 25.0° to the horizontal. A force F is applied to the object at 44.0° to the horizontal, pushing it upward on the plane. The coefficients of static and kinetic friction between the block and the plane are, correspondingly, 0.352 and 0.146.
