3.75 J

Explanation:

First, in solving the equation, convert the given unit to kl. and meter before applying to the formula:

KE = 1/2 mv^2

Where mass(m) is in kilograms(kl) and velocity (v) in meters.

Conversion: 300g÷1000=0.3kl. : 500cm÷100=5m

Applying to the Formula:

KE = 1/2 mv^2

KE = 1/2 (0.3kl.) x (5m)^2

KE = 1/2 (7.5)

KE = 3. 75 joules
