A wheeled cart with a mass of 0.50 kg is rolling along a horizontal track at a constant velocity of 2.0 m/s when it experiences an elastic collision with a second identical cart that is initially at rest, and attached to a spring with a spring constant of 4.0 N/m. After the collision, the second cart moves to the right. What is the maximum compression of the spring?
A 0.16-kg ball on a stick is whirled on a vertical circle at a constant speed. Find the tension in the stick
find the mass of Earth from the period T and the radius r of the Moon's orbit about the Earth. T=27.3 days and r=3.82E5 km. suppose the Moon orbits the center of Earth rather than the center of mass of the Earth-Moon system.
A 13 g bullet traveling 217 m/s penetrates a 2 kg block of wood and emerges cleanly at 153 m/s. If the block is stationary on a frictionless surface when hit, how fast does it move after the bullet emerges.
