Explain why the motion of someone jumping up and down on a trampoline is not simple harmonic motion. (Their feet lose contact with the trampoline during each bounce.)

Use the graphs shown in Figure to determine the values of the following quantities:

Amplitude

Use the graphs shown in Figure to determine the values of the following quantities: Time period

Use the graphs shown in Figure to determine the values of the following quantities:

Maximum velocity

Use the graphs shown in Figure to determine the values of the following quantities:

Find the maximum acceleration

State at what point in an oscillation the oscillator has zero velocity but positive acceleration.

Look at the $x-t$ graph of Figure (a). When $t=0.1 \mathrm{s}$, what is the gradient of the graph? State the velocity at this instant.

Figure shows the displacement-time $\left(x-t\right)$ graph for an oscillating mass. Use the graph to determine the following quantities the velocity in ${\mathrm{cms}}^{-1}$ when $t=0 s$.
