A225-g object is attached to a spring that has a force constant of 74.5 n/m. the object is pulled 6.25 cm to the right of equilibrium and released from rest to slide on a horizontal, frictionless table.
(a) calculate the maximum speed of the object.
(b) find the locations of the object when its velocity is one-third of the maximum speed. treat the equilibrium position as zero, positions to the right as positive, and positions to the left as negative.

1.137278672 m/s

+5.9 cm or -5.9 cm

Explanation:

A = Amplitude = 6.25 cm

m = Mass of object = 225 g

k = Spring constant = 74.5 N/m

Maximum speed is given by

The maximum speed of the object is 1.137278672 m/s

Velocity is at any instant is given by

The locations are +5.9 cm or -5.9 cm

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
