Concept

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:

K=12mv2

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

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