A mass 1.2 kg is attached to a spring on a friction-less air track. the mass is resting in equilibrium. A 10-gram bullet is fired into the mass to initiate oscillatory motion. The bullet hits mass from the left @ 120 m/s at t=0 and gets lodged inside of it. Period 15 seconds.
Bullet KE 72J After bullet strike KE 0.595J Initiall Velocity 0.992 m/s
Find the amp and phase constant of the resulting oscillations. then write an explcit exp for position xt and velocity vt of the mass as a func of time
