A 0.66 kg block attached to a spring with force constant 150 N/m
is free to move on a frictionless, horizontal surface as in the
figure below. The block is released from rest after the spring is
stretched 0.13 m.
(a) At that instant, find the force on the block.
N?
(b) At that instant, find its acceleration.
m/s^2?
Homework Answers
F=-(150N/m)(.13m)
F=-19.5N
The negative sign indicates this force is restoring equilibrium.
b) Now you can use F=ma to find the acceleration:
a=F/m
a=19.5N/.66kg=29.55m/s^2
