Aconveyer belt moves a 40 kg box at a velocity of 2 m/s. what is the kinetic energy of the box while it
conveyor belt?
40 j
80 3
160 j
1,600 )

K.E = 80 j

Explanation:

Given data:

Mass of box = 40 Kg

Velocity = 2 m/s

K.E = ?

Solution:

K.E = 1/2 m.v²

K.E = 1/2 (40 Kg) (2 m/s)²

K.E = 1/2 (40 Kg) (4m²/s²}

K.E = 1/2 (160 Kg. m²/s²)

K.E = 80 Kg. m²/s²

Kg. m²/s² = j

K.E = 80 j
