Answer:
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
Kinetic energy of the box=80J
Explanation:
mass of the box=40 Kg
velocity of box= 2 m/s
Kinetic energy= 1/2 mV²
KE= 1/2 (40)(2)²
KE=80J
Thus kinetic energy of the box=80 J
