moving?

Use the formula:

E = (1/2) * m * v ^2

For unit consistency, make sure that:

E energy is in joules (J)
m mass is in kilograms (kg)
v velocity is in meters per second (m/s)
So, substituting to the equation:

14= (1/2) * (17) * v^2

By algebraic manipulation, we derive:

v = (2*14/17)^0.5

v = 1.2834 m/s
