Aconcrete block is hung from an ideal spring that has a force constant of 100 n/m . the spring stretches 0.129 m .a- what is the mass of the block? b- what is the period of oscialltion of the block if it is pulled down 1 cm and released? c- what would be the period of oscillation if the block and spring were placed on the moon?

1.31498 kg

0.72050 s

0.72050 s

Explanation:

m = Mass of block

g = Acceleration due to gravity = 9.81 m/s²

k = Spring constant = 100 N/M

x = Displacement = 0.129 m

The force balance is

The mass of the block is 1.31498 kg

Time period is given by

The period of oscillations is 0.72050 s

The time period does not depend on the acceleration due to gravity. It varies with the mass and the spring constant.

Hence, the time period would be the same

v=ir = 3x15 =45 v
