One end of a horizontal string is moved up and down twice per second with a maximum vertical displacement of 12.0 cm above and 12.0 cm below its equilibrium point. The string has a linear mass density of 35.0 g/m, and its tension is 15.0 N. How much energy per second is being supplied to the string? i W Save for Later Submit Answer

A 3 kg object connected to a light spring with a spring constant of 120 N/m oscillates on a frictionless horizontal surface. a) Calculate the kinetic energy of the object when the speed is 0.5 m/s? b) Calculate the spring potential energy (or elastic potential energy) when the object is at the position 3 cm.

1) c) A block on a frictionless surface is connected to a 10N/m spring. A velocity vs. time graph is given below. Sketch position vs. time and acceleration vs. time graphs with appropriate details. Determine the maximum displacement and maximum acceleration using forces and/or energy principles (i.e. not calculus). Include appropriate diagrams and/or bar charts for determining these quantities. Determine the equations that correspond to each of the graphs including numerical values where appropriate. Determine the mass of the block. Show your work.

Convert the following to basic SI units or a combination of basic Sl units:

A 0.500 kg stone is moving in a vertical circular path attached to a string that is 75.0 cm long. The stone is moving around the path at a constant frequency of 2.20 rev/sec. At the moment the stone is overhead, the stone is released. The velocity of the stone when it leaves the circular path is   Multiple Choice   10.4 m/s horizontal.   10.4 m/s vertical.   22.0 m/s horizontal.   22.0 m/s vertical.   31.4 m/s horizontal.

A 6.13-kg object oscillates back and forth at the end of a spring whose spring constant is 55.4 N/m. An observer is traveling at a speed of 2.80 x 108 m/s relative to the fixed end of the spring. What does this observer measure for the period of oscillation? Number i Units
