Question

An object has kinetic energy of 25 J and a mass of 34 kg how fast is the object moving?

Answer 1

Equation:

Kinetic energy = 1/2 mv^2

velocity =
`\sqrt{(2KE)/(m) }`

work:

m = 34 kg

kinetic energy = 25 J

velocity =
`\sqrt{(2(25))/(34) } = \sqrt{(50)/(34) } = 1.212678125`

Answer with units: 1.21 m/s
