A0.50-kg box is attached to an ideal spring of force constant (spring constant) 20 n/m on a horizontal, frictionless floor. the box oscillates in simple harmonic motion and has a speed of 1.5 m/s at the equilibrium position. (a) what is the amplitude of vibration

Explanation:

As we know that for spring block system the angular frequency is given as

now we know that

also we know that

so we have

now we know that speed of an SHM at its equilibrium position is given as

now plug in all values in it

double the distance = divide strength by 4
