A0.100-kllogram apple falls "am a height m150 metals to 1 00 meters, ignoring fricfiona| effeds, what is the kmeflc
energy loe apple at lhls height?

The kinetic energy of an apple at 100 m of height while falling is 49 J.

Explanation:

Mass of the apple = 0.100 kg

Height at that instant when apple was at verge of falling = 150 m

The sum of the potential energy and kinetic remains constant.

Sum of P.E and K.E energy at height if 150 m

Kinetic energy is zero at initial position

Sum of P.E and K.E at height if 100 m

Kinetic energy is not zero during falling of an apple

K.E = 147 J - 98 J= 49 J

The kinetic energy of an apple at 100 m of height while falling is 49 J.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
