The force required to stretch a Hooke’s-law spring varies from 0 N to 76.4 N as we stretch
the spring by moving one end 14.6 cm from
its unstressed position.
Find the force constant of the spring.
Answer in units of N/m.

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping
