Physics 1A FINAL 1) Consider the motion of the 3 kg block on the horizontal surface when acted upon by the force F = 10 N indicated. The coefficient of friction, u^, between the block and the horizontal surface is 0.20. If the 3kg mass starts from rest, how far does it travel before reaching a velocity of 25 m/s.

2) A solid cylinder is initially moving along a flat surface without rotating. Due to the action of friction, it eventually begins rolling without slipping. The coefficient of friction is 0.22, the radius of the cylinder is 0.5 m, its mass is 2.7 kg and its initial center of mass velocity is 1.5 m/s. co = 0 a) How long does it take to reach a rolling without slipping condition? b) What is the total energy change of the system between the initial condition and the establishment of rolling without slipping?
3) A bullet of mass m = 8 g moving with velocity v = 200 m/s strikes the edge of a cylinder of mass M = 6.00 kg and radius R 0 = 28.0 cm. (I = MR 0 2 /2) The bullet penetrates the cylinder and emerges from the other side with v' = 150 m/s. The
