Question

A solid cylinder of mass 3 kg rolls at 4 m/s on a horizontal surface, compressing a spring of force constant 200 N/m. Find maximum compression.

G1 Physics · Accepted Answer

Step 1: Rolling kinetic energy is ½mv²(1+½)=¾×3×16=36 J. Step 2: At maximum compression ½kx²=36, so 100x²=36, x=0.6 m. Final answer: B — 0.6 m.
