The wooden block is attached to a spring and lies on a frictionless table. If the colision is inelastic and the spring constant A-15.0 im

Explanation / Answer

Question 1) v = x * sqrt [ k / m ]

component of gravity parallel to the incline a = -g * sin theta

vf2 = vi2 + 2 a d

d= -vi2 / 2 a = (x2 * k) / (2 m g sin theta )

= (0.1002 * 24.9) / (2 * 56.8 * 10-3 * 9.8 * sin 46)

d = 0.311 m
