Question

A fisherman's scale stretches 4.0 cm when a 2.5 kg fish hangs from it.

A) What is the spring stiffness constant??

B) What will be the amplitude of vibration if the fish is pulled down 2.5 cm more and released so that it vibrates up and down?

C) What will be the frequency of vibration if the fish is pulled down 2.5 cm more and released so that it vibrates up and down?

A spring stretches 0.150 m when a 0.300 kg. mass is hung vertically from it. From this information you can determine the spring constant, k. Next, the spring is set up horizontally with the 0.300 kg. mass resting on a frictionless table. The block is pushed so that the spring is compressed 0.100 m from the equilibrium point, and released from rest. Determine: The spring constant k (in N/m)? The amplitude of the horizontal oscillation (in m)? The angular frequency,...
