Question

Explain how to answer the question on this picture

Answer 1

The maximum speed of the particle (2.0 g) that oscillates as shown by the graph is 63.2 m/s

How to determine the maximum speed?

First, we shall obtain the energy of the particle as shown from the question. Details below:

• Maximum energy = 5 J
• Minimum energy = 1 J
• Energy of particle =?

Energy of particle = Maximum energy - minimum energy

= 5 - 1

= 4 J

Finally, we shall calculate the maximum speed of the particle. Details below:

• Energy of particle (E) = 4 J
• Mass of particle (m) = 2.0 g = 2 / 1000 = 0.002 Kg
• Maximum speed of particle (v) =?

`v = \sqrt{(2E)/(m)} \\\\v = \sqrt{(2\ *\ 4)/(0.002)}\\\\v = 63.2\ m/s`
