If a car travelling at 63 km/h will skid 18 m when its brakes lock, how far will it skid if it is travelling at 150 km/h while its brakes lock.
An oscillating LC circuit has a current amplitude of 7.50 mA, a potential amplitude of 250 mV, and the capacitance of 220 nF. What are (a) the period of oscillation.
A compressed spring shoots the block radically outward along a frictionless groove in the surface of the turntable. Illustrate what is the turntable's rotation angular velocity when the block reaches the outer edge?
A 878 kg car has four 11.8 kg wheels. When the car is moving, what fraction of the total kinetic energy of the car is due to rotation of the wheels about their axles
A cardinal (Richmondena cardinalis) of mass 3.60×10-2 and a baseball of mass 0.146 have the same kinetic energy. What is the ratio of the cardinal's magnitude of momentum to the magnitude of baseball's momentum.
