Question

(Figure 1) represents the motion of a mass on a spring.

1.What is the amplitude of the oscillation

What is the position of the mass at time t = 30s ?

When is the first time the velocity of the mass is zero?

At which of these times does the kinetic energy have its maximum value

Explanation / Answer

Amplitude = 4.5 cm (approx)

the position of the mass at time t = 30s, x=-2.5 (approx)

first time the velocity of the mass is zero at t=2.5 s (approx)

the kinetic energy have its maximum value at t=8, 20, 32, 44 s (approx)
