question 32

Multiple Choice

A 12-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)0.78 m/s
• B)0.81 m/s
• C)0.71 m/s
• D)0.58 m/s
• E)0.64 m/s
