Question

A: A ball of mass m is attached to a spring with constant k and is released from rest at vertical position y0. Just before the ball is released the spring is in the equilibrium. The ball first stretches the spring and then starts oscillating between positions y1 and y2. Find them.

B: Do the same for the ball placed on top of the spring at height y0. In this case the ball squeezes the spring first.

C: Do the same if the ball is attached between two springs, with coefficients k1 (top spring) and k2 (bottom spring).

D: Do the same if the block of mass m is placed on a plane with smooth surface inclined at angle ? to the horizontal and is attached to two springs with constants k1 (top spring) and k2 (bottom spring).

A: Sting hanging from ceiling holding a spring that holds a string that holds a ball

B: "A" but upsidedown

C: Both "A" and "B" combined with only one ball in the middle.

D: A right triangle, long leg horizontal, with two "sticks" on the corners of the hypotonuse that hold springs with a nolck between the springs touching the hypotonuse.

Explanation / Answer

y1=(mg/k)+y0

y2=y0-(mg/k)
