1. Understand the Formula

The formula for kinetic energy (KE) is:

KE = (1/2) * mv²

Where:

* KE = Kinetic energy (in joules)

* m = mass (in kilograms)

* v = velocity (in meters per second)

2. Rearrange the Formula to Solve for Velocity (v)

* 2KE = mv²

* v² = 2KE / m

* v = √(2KE / m)

3. Plug in the Values

* KE = 300 joules

* m = 0.05 kilograms

v = √(2 * 300 joules / 0.05 kilograms)

4. Calculate

v = √(12000) ≈ 109.54 meters per second

Therefore, the object will be moving at approximately 109.54 meters per second.
