Q1. A 10.4-kg cylinder rolls without slipping on a rough surface. At an instant while its center of gravity has a speed of 12.1 m/s, find out the rotational kinetic energy about its center of gravity.

Q2. A 600 turn solenoid, 25 cm long, has a diameter of 2.8 cm. A 10 turn coil is wound tightly around the center of the solenoid. If the current in the solenoid increases uniformly from 0 to 5.0 A in 0.48 s, what would be the induced emf magnitude in the short coil during this time?

Q3. A system does 238 J of work on its environment and gains 84.7 J of heat in the process. Find the change in the internal energy of (a) system and (b) environment.
