The position of a 0.30-kg object attached to a spring isdescribedby

(a) Find the amplitude of the motion.
m

(b) Find the spring constant.
N/m

(c) Find the position at t = 0.29 s.

A truck covers 40.0 m in 8.90 s whilesmoothly slowing down to afinal velocity of 2.30 m/s.

Neglecting friction every where, find the acceleration of M. Assume m>m′
