Q. A massless spring with spring constant 22.1 N/m hangs vertically. A body of mass 0.280 kg is attached to its free end and then released. Assume that the spring was unstretched before the body was released. How far below the initial position does the body descend?
Q. A tuning fork vibrating at 510 Hz falls from rest and accelerates at 9.80 m/s2. How far below the point of release is the tuning fork when waves of frequency of 482 Hz reach the release point? (Take the speed of sound in air to be 343 m/s.)
