A block whose mass is 2kg is fastened to a spring. The spring has a spring constant of 100 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 5 cm away from the mean position.

1.	A block whose mass is 2kg is fastened to a spring. The spring has a spring constant of 100 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 5 cm away from the mean position.
Answer» SOLUTION :Kinetic ENERGY `=0.19J`, Potential energy `=0.0625 J`, Total energy `=0.25J`.
