A 20 kg child is on a swing that hangs from 2.2-m-long chains. Part A What is her maximum speed if she swings out to a 49° angle? Express your answer to two significant figures and include the appropriate units. v=Value
In an electric shaver, the blade moves back and forth over a distance of 2.0 mm. The motion is simple harmonic, with frequency 110 Hz. (a) Find the amplitude. mm (b) Find the maximum blade speed. m/s (c) Find the maximum blade acceleration. m/s2
A simple harmonic oscillator consists of a block attached to a spring, moving back and forth on a frictionless horizontal surface. Suppose the mass of the box is 5.0 kg. The motion is started by holding the box at .50m from its central position, using a force of 40.0 N. Then the box is let go and allowed to perform simple harmonic motion. What is the amplitude of the motion? What is the spring constant k? What is the maximum...
15) In an electric shaver, the blade moves back and forth over a stance of 2.0 mm in simple harmonic motion, with frequency 100 Hz. Find (a) the amplitude, (b) the maximum blade speed, and (c) the magnitude of the maximum blade acceleration. 20 An oscillating block-spring system has a mechanical energy of 2.00 J, an amplitude of 10.0 cm, and a maximum speed of 0.800 m/s. Find (a) the spring constant, (b) the mass of the block, and (c)...
A spider of mass m is swinging back and forth at the end of a strand of silk of length L. During the spider's swing the strand makes a maximum angle of θ with the vertical. What is the speed of the spider at the low point of its motion, when the strand of silk is vertical? Express your answer in terms of the variables m, θ, L, and g. A spider of mass m is swinging back and forth...
A simple harmonic oscillator consists of a block attached to a spring, moving back and forth on a frictionless horizontal surface. Suppose the mass of the box is 5.0 kg.
