Question

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

Answer 1

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
