Answer #1

Solution:

Given,

spring constant k=270N/m

mass m=83 Kg

The mass is streched to a distance of 5m. Therefore, amplitude a =5m.

The angular velocity is given by,

(a)The displacement of a body in SHM is given by,.  

  

i.e,

so, at t= 2 s

  

(b) The velocity of the body is given by,
