A 0.5kg mass suspended from a spring oscillates with a period of 1.5s. How much mass must be addedto the object to change the period to 2s?

A 13,000N car starts at rest and rolls down a hill from a height of 10m. It then moves across a level surface and collides with a light spring-loaded guardrail. Neglecting any losses due to friction, and ignoring the rotational kinetic energy of the wheels, find the maximum distance the spring is compressed. Assume a spring constant of 1*10⁶N/m.

A 13,000N car starts at rest and rolls down a hill from a height of 10m. It then moves across a level surface and collides with a light spring-loaded guardrail. Neglecting any losses due to friction, and ignoring the rotational kinetic energy of the wheels, assume a spring constant of 1*10⁶N/m. Calculate the magnitude of the car's maximum acceleration after contact with the spring, assuming no frictional losses.

A pendulum that has a period of 3s and that is located where the acceleration due to gravity is 9.79m/s² is moved to a location where the acceleration due to gravity is 9.82m/s². What is the new period?

A spring has a length of 0.2m when a 0.3kg mass hangs from it, and a length of 0.75m when a 1.95kg mass hangs from it. What is the spring constant?

A stroboscope is set to flash every 0.00008s. What is the frequency of the flashes?

A type of cuckoo clock keeps time by having a mass bouncing on a spring, usually something cute like a cherub in a chair. What force constant is needed to produce a period of 0.5s for a 0.015kg mass?

A wave has a wavelength of 3m. Calculate the frequency of the wave if it is a sound wave. Take the speed of sound to be 343m/s.

A wave has a wavelength of 3m. Calculate the frequency of the wave if it is a light wave. Take the speed of light to be 3*10⁸m/s. Enter the number that would be multiplied by 10⁸.

Fish are hung on a spring scale to determine their mass. What is the force constant of the spring in such a scale if the spring stretches 8cm for a 10kg fish?

If your heart rate is 150 beats per minute during strenuous exercise, what is the time per beat in units of seconds?

One type of BB gun uses a spring-driven plunger to blow the BB from its barrel. Calculate the force constant of its plunger's spring if you must compress it to 0.15m to drive the 0.05kg plunger to a top speed of 20m/s.

Radio waves transmitted through space at 3*10⁸m/s by the Voyager spacecraft have a wavelength of 0.12m. What is their frequency? Your answer will be on the order of 10⁸Hz.

Scouts at a camp shake the rope bridge they have just crossed and observe the wave crests to be 8m apart. If they shake the bridge twice per second, what is the propagation speed of the waves?

Storms in the South Pacific can create waves that travel all the way to the California coast, which are 12,000km away. How long does it take them (in seconds) if they travel at 15m/s?

The length of nylon rope from which a 63kg mountain climber is suspended has a force constant of 14,000 N/m. How much would this rope stretch to break the climber's fall if he free falls 2m before the rope runs out of slack?

The pendulum on a cuckoo clock is 5cm long. What is its period?
