A12 g plastic ball is dropped from a height of 2.5 m and is moving at 3.2 m/s just before it hits the floor. how much mechanical energy was lost during the fall?

0.24

Explanation:

Mass of ball= 12g=0.012Kg

height of ball= 2.5m

velocity of ball before falling= 3.2m/s

potential energy of the ball=mgh= 0.012*10*2.5=0.3J

kinetic energy of the ball=0.5*m=0.5*0.012*3.2*3.2=0.6J

Loss in mechanical energy during the fall= potential energy- Kinetic energy= 0.3-0.06=0.24J

note: During the fall, the potential energy of the ball is converted to kinetic energy. the loss in energy is due to air resistance.

where's the following? you gotta add it to know what the choices are

explanation:

correct it is c.) b b
