A bullet traveling at 289 m/s collides with a box and, slides across a smooth surface, which is attached
at one end to a handle. If a torque of 25.0 N*m is required to open the door, how long will it
take for the block/ bullet combo to slide far enough on the lever to open the door? The mass of
the block is 0.44 kg, and the mass of the bullet 3.0x10-3 kg. Assume the lever is perpendicular to
the ground.

Mass A (8.5 kg) slides across a frictionless surface with a velocity of 6 m/s in the positive direction. Mass B (8.5 kg) slides across the same surface in the opposite direction with a velocity of ?12 m/s. The two objects collide and stick together after the collision. Calculate the center-of-mass velocity (in m/s) of the system both before and after the collision. (Indicate the direction with the sign of your answer.)
