1. A small electric device has a resistance of 15 ohms when the current in it is 0.5 amperes. Calculate the voltage required to produce this current.
2. Calculate the velocity of a car (in m/s) that starts from rest and accelerates at 1 m/s2 for 6 seconds.
3. Calculate the centripetal acceleration of a 2 kg mass (in m/s2) if it is attached to a 0.5 m rope and revolves at a speed of 16 m/s?
4. The mass of a train is 27,666 kg. If the train accelerates at 1.1 m/s2, what net force (in Newtons) acts on the train?
5. The kinetic energy of a motorcycle and driver is 57,068 J. If their total mass is 500 kg, what is their velocity (in m/s)?
6. Calculate the momentum of a 265 kg motorcycle traveling at 65 m/s.
