Question

Fish are hung on a spring scale to determine their mass (most fishermen feel no obligation to report the mass truthfully).
(a) What is the force constant (in N/m) of the spring in such a scale if it stretches 8.40 cm for a 14.0 kg load?
| N/m
(b) What is the mass (in kg) of a fish that stretches the spring 5.50 cm?
|kg
(c) How far apart (in mm) are the half-kilogram marks on the scale?
mm

The systems shown below are in equilibrium with m= 20 kg and ? = 28.0°. If the spring scales are calibrated in newtons, what do they read? Ignore the masses of the pulleys and strings and assume the pulleys and the incline are frictionless.
2. Construct a problem where a mass is sitting on top of a spring inside an elevator; both are suspended by a rope and are uniformly accelerating upwards with magnitude 4 meters per second squared. Specify all the masses in the problem, as well as all the forces acting in the problem, and their relative directions.
A spring has a length of 0.298 m when a 0.300 kg mass hangs from it, and a length of 0.750 m when a 3.12 kg mass hangs from it. (Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.) (a) What is the force constant of the spring?

A 475.-g mass at rest on the end of a horizontal spring with spring constant 925. N/m is struck by a hammer which gives it an initial speed of 3.00 m/s. Determine the maximum acceleration (in m/s/s) that the mass experiences as it oscillates. (What equation can I use to solve the maximum acceleration?)
