What’s the velocity of a ball falling with 100 joules of kinetic energy and a mass of 2 kilograms? Use the formula, .
A.3 m/s
B.5 m/s
C.7 m/s
D.8 m/s
E.10 m/s

Respuesta :

kinetic energy = 0.5*m*velocity square.
solving we get velocity =10 metre /sec

Answer:

The velocity will be 10 m/s

Explanation:

Look at the picture below
