4. An 85 kg object has 2.16 x 10 J of kinetic energy. What is the object's velocity?

v = 0.713[m/s]

Explanation:

Kinetic energy is defined as the product of mass by the squared velocity of a body. In this way with the following expression we can have the kinetic energy as a function of velocity.

where:

m = mass = 85 [kg]

v = velocity [m/s]

Ekin = kinetic energy = 2.16*10 [J]

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete
