A small block is attached to an ideal spring and is moving in SHM on a horizontal, frictionless surface. The amplitude of the motion is 0.290 m and the period is 3.01 s . Part A What is the acceleration of the block when x

Explanation:

ω = 2π/ T = 2π/ 3.01 = 2.087 rad/s

x(t) = 0.290sin2.087t

v(t) = 0.290(2.087)cos2.087t

a(t) = -0.290(2.087²)sin2.087t

With these three equations, you should be able to plug in what you know to find other values

12000j is work done

the independent variable, or the one that is intentionally manipulated is the speed.
