Aconveyer belt moves a 40 kg box at a velocity of 2 m/s. what is the kinetic energy of the box while it is on the conveyor belt?

Answer : The kinetic energy of the box is, 80 J

Explanation :

The formula used for kinetic energy is:

where,

K.E = kinetic energy = ?

m = mass = 40 kg

v = velocity = 2 m/s

Now put all the given values in the above formula, we get the kinetic energy of the box while it is on the conveyor belt.

Thus, the kinetic energy of the box is, 80 J

the answer is b

explanation:

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
