# Problem: Problem: A block oscillating on a spring has a maximum speed of 20cm/s. What will be the block's maximum speed if its total energy is doubled? Explain.

###### FREE Expert Solution

At maximum speed, all the energy of the block is kinetic energy.

Kinetic energy:

$\overline{){\mathbf{K}}{\mathbf{=}}\frac{\mathbf{1}}{\mathbf{2}}{{\mathbf{mv}}}^{{\mathbf{2}}}}$

Here, v = 20cm/s = 0.2 m/s

If we double the energy, the new energy will be:
