Hey! the answer would be the sun. sunlight is needed to produce natural sugars and glucose. hope that helps ;)
speed of the plane is given as

height of the plane is

acceleration due to gravity is

part a)
when package is dropped its vertical speed is zero so we can use kinematics to find the time of drop



Part b)
Horizontal distance moved by the package is given by



Part c)
final speed in x direction

final speed in y direction

so net speed as it hit the ground will be



Answer:
PE=mgh
KE=<u>1</u> mv²
2
hope its helpful for u ..
The basketballs and racquetball eventually stopped bouncing due to the first law. the first law states that an object at rest will stay at rest unless acted upon by an external force. this means that once the 2 balls lose friction, they will remain at rest until acted upon by an external force. once the 2 balls lose friction(energy), they come to a complete stop.
