A toy mouse has a mass of 10 kg and kinetic energy of 5 j what is its speed

Answer:1m/s

Explanation:

Mass (m) = 10kg

Kinetic energy (ke) = 5j

Velocity (v) = ?

Ke = (m x v^2) / 2

5 = (10 x v^2) / 2

Cross product

5 x 2=10 x v^2

10=10 x v^2

Divide both sides by 10

10/10 = (10 x v^2) / 10

1=v^2

v^2=1

v=√ (1)

v=1m/s
