A block whose mass is 1kg is fastened to a spring. The spring has a spring constant of 50 Nm^(-1). The block is pulled to a distance x=10 cm from its equilibrium position at x=0 on a frictionless surface from rest at t=0. Calculate the kinetic, potential and total energies of the block when it is 7.07 cm away from the mean position.

1.	A block whose mass is 1kg is fastened to a spring. The spring has a spring constant of 50 Nm^(-1). The block is pulled to a distance x=10 cm from its equilibrium position at x=0 on a frictionless surface from rest at t=0. Calculate the kinetic, potential and total energies of the block when it is 7.07 cm away from the mean position.
Answer» Solution :KINETIC ENERGY `=0.125J`, POTENTIAL energy `=0.125 J`, TOTAL energy `=0.25 J`.
