Multiple Choice
A 10-kg block on a horizontal frictionless surface is attached to a light spring (force constant = 0.80 kN/m) .The block is initially at rest at its equilibrium position when a force (magnitude P = 80 N) acting parallel to the surface is applied to the block,as shown.What is the speed of the block when it is 13 cm from its equilibrium position?
A) 0.85 m/s
B) 0.89 m/s
C) 0.77 m/s
D) 0.64 m/s
E) 0.52 m/s
