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. calculate the maximum speed of the object.
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.

Part b)

Explanation:

Part a)

As we know that the maximum speed of the spring block system is given as

so we have

so we have

now we have

Part b)

speed of the object at a distance x from its mean position is given as

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
