A 10 kg metal block is attached to a spring of springconstant 1000 N m^(-1). A block is displaced from equilibrium position by 10 cm and released. The maximum acceleration of the block is

Answer»

10 `ms^(-2)`
100`ms^(-2)`
200`ms^(-2)`
0.1 `ms^(-2)`

SOLUTION :`k=1000 Nm^(-1)`, extention x=10 CM =0.1 m
`:.` Magnitude of restoring force `F=kx=1000xx0.1=100N`
ACCELERATION `a=F/m=(100)/(10)`
`:.a=10 m//s^2`
