Q1. A 80-g ball collides elastically with a 350-g ball that is at rest. If the 80-g ball was travelling in the positive x-direction at 5.85 m/s before the collision, what are the velocities of the two balls after the collision?
Q2. A rifle with a barrel length of 62 cm fires a 12 g bullet with a horizontal speed of 460 m/s/s. The bullet strikes a block of wood and penetrates to a depth of 15 cm.
How long does it take the bullet to come to rest?
A 500 turn solenoid with a length of 20 cm and a radius of 3.0 cm carries a current of 3.0 A. A second coil of four turns is wrapped tightly about this solenoid so that it can be considered to have the same radius as the solenoid. Find when the curre..
