Fish is hung on a spring scale to determine their mass fishermen feel no obligation to truthfully report the mass.

a. What is the force constant of the spring in such a scale if it the spring stretches 8.00 for a 10.0 kg load.

b. What is the mass of a fish that stretches the spring 5.50cm

c. How far apart are the half-kilogram marks on the scale?

It is weigh-in time for the local under-85-kg rugby team. The bathroom scale used to assess eligibility can be described by Hooke's law and is depressed 0.75 cm by its maximum load of 120 kg. (a) What is the spring's effective spring constant? (b) A player stands on the scales and depresses it by 0.48 cm. Is he eligible to play on this under-85 kg team?

A stroboscope is set to flash every 8.00 X 10-5 s. What is the frequency of the flashes?

Suppose you attach the object with mass m to a vertical spring originally at rest, and let it bounce up and down. You release the object from rest at the spring's original rest length. (a) Show that the spring exerts an upward force of 2.00mg on the object at its lowest point. (b) If the spring has a force constant of 10.0 N/m and a 0.25-kg-mass object is set in motion as described, find the amplitude of the oscillations. (c) Find the maximum velocity.

What is the effect on the period of a pendulum if you double its length?

What is the effect on the period of a pendulum if you decrease its length by 5.00%?
