A 200 g oscillator in a vacuum chamber has a frequency of 2.0 Hz. When air is admitted, the oscillation decreases to 60% of its initial amplitude in 50 s. How many oscillations will have been completed when the amplitude is 30% of its initial value?
A 1.00 kg block is attached to a horizontal spring with spring constant 2500 N/m. The block is arrest on a frictionless surface. A 10.0 g bullet is fired into the block, in the face opposite the spring, and sticks. Part A What was the bullet’s speed if the subsequent oscillations have an amplitude of 10.0 cm? Part […]
A spring with spring constant 15.0 N/m hangs from the ceiling. A ball is suspended from the spring and allowed to come to rest. It is then pulled down 6.00 cm and released. If the ball makes 30 oscillations in 20.0 s, what are its (a) mass and (b) maximum speed? Part A What is the mass of […]
A spring has an unstretched length of 12 cm. When an 80 g ball is hung from it, the length increases by 4.0 cm. Then the ball is pulled down another 4.0 cm and released. Part A What is the spring constant of the spring? Part B What is the period of the oscillation? Part C Draw […]
