A 3,000 kg truck travelling at 50 km/hr strikes a stationary 1,000 kg car, locking the two vehicles together.
a) What is the final velocity of the two vehicles?
b) How much of the kinetic energy is lost to the collision?
Suppose you had a machine for 100% efficiently transferring kinetic energy of a rotating bicycle pedal to electrical energy. If the mass of a pedal is 200 g, (a) how fast must the pedal be moving to power a 17.00 W LED light? (b) what is the angular speed, in rpm, if the distance from the centre of the crank to the pedal is 16 cm?
