To practice problem-solving strategy: simple harmonic motion ii: energy. a child's toy consists of a spherical object of mass 50 g attached to a spring. one end of the spring is fixed to the side of the baby's crib so that when the baby pulls on the toy and lets go, the object oscillates horizontally with a simple harmonic motion. the amplitude of the oscillation is 6 cm and the maximum velocity achieved by the toy is 3.2 m/s . what is the kinetic energy k of the toy when the spring is compressed 3.7 cm from its equilibrium position?

0.15864 J

Explanation:

m = Mass of toy = 50 g

A = Amplitude = 6 cm

x = Compression of spring = 3.7 cm

= Maximum velocity = 3.2 m/s

The kinetic energy of the system is given by

The kinetic energy of the toy is 0.15864 J

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
