Weighing Lunch
For lunch you and your friends decide to stop at the nearestdeli and have a sandwich made fresh for you with 0.100 kg ofturkey. The slices of turkey are weighed on a plate of mass 0.400kgplaced atop a vertical spring of negligible mass and forceconstant of 200 N/m . The slices of turkey are dropped on the plateall at the same time from a height of 0.250 m . They make a totallyinelastic collision with the plate and set the scale into verticalsimple harmonic motion (SHM). You may assume that the collisiontime is extremely small.
Part A
What is the amplitude of oscillations A of the scaleafter the slices of turkey land on the plate?
Express your answer numerically in meters and take free-fallacceleration to be g = 9.80 m/s2 .
A = ?? m
Part B
What is the period of oscillation T of the scale?
Express your answer numerically in seconds.
T = ?? s
