A simple harmonic oscillator consists of a block of mass 0.84 kg attached to a spring (k = 275 N/m). The block slides on a horizontal frictionless surface about the equilibrium point x = 0 with a total mechanical energy of 4.0 J. (a) What is the amplitude of the oscillation? Additional questions (with their own answer boxes below), and to be included in your written work: (b) How many oscillations does the block complete in 15 s? Note: this number can have a decimal part; it doesn't have to be a whole number. (c) What is the maximum kinetic energy attained by the block (in J)? (d) What is the magnitude of the maximum acceleration that the block experiences (in m/s")?

A simple harmonic oscillator consists of an $0.80 \mathrm{~kg}$ block attached to a spring $(k=200 \mathrm{~N} / \mathrm{m})$. The block slides on a horizontal frictionless surface about the equilibrium point $x=0$ with a total mechanical energy of $4.0 \mathrm{~J}$. (a) What is the amplitude of the oscillation? (b) How many oscillations does the block complete in $10 \mathrm{~s} ?(\mathrm{c})$ What is the maximum kinetic energy attained by the block? (d) What is the speed of the block at $x=0.15 \mathrm{~m} ?$
A simple harmonic oscillator consists of a 0.50 $\mathrm{kg}$ block attached to a spring. The block slides back and forth along a straight line on a frictionless surface with equilibrium point $x=0 .$ At $t=0$ the block is at $x=0$ and moving in the positive $x$ direction. A graph of the magnitude of the net force $\vec{F}$ on the block as a function of its position is shown in Fig. $15-55$ . The vertical scale is set by $F_{s}=$ 75.0 $\mathrm{N}$ . What are (a) the amplitude and (b) the period of the motion, (c ) the magnitude of the maximum acceleration, and (d) the maximum kinetic energy?
A simple harmonic oscillator consists of a block attached to a spring with $k=200 \mathrm{N} / \mathrm{m}$ . The block slides on a frictionless surface, with equilibrium point $x=0$ and amplitude 0.20 $\mathrm{m} .$ A graph of the block's velocity $v$ as a function of time $t$ is shown in Fig. $15-60 .$ The horizontal scale is set by $t_{s}=0.20$ s. What are (a) the period of the SHM, (b) the block's mass, (c) its displacement at $t=0,(\mathrm{d})$ its acceleration at $t=0.10 \mathrm{s},$ and ( e ) its maximum kinetic energy?
