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

it is the second option.

d is the correct answer
