Answer:
180.4 m
Explanation:
The package in relation to the point where it was released falls a certain distance that is calculated by applying the horizontal motion formulas , as the horizontal speed of the plane and the height above the ground are known, the time that It takes the package to reach its destination and then the horizontal distance (x) is calculated from where it was dropped, as follows:
h = 100 m
x =?
Height formula h:
Time t is cleared:
t = 4.51 sec
Horizontal distance formula x:
x = 40 m / sec x 4.51 sec
x = 180.4 m

Answer:
The energy that is radiated to Earth by the Sun includes visible light, infrared radiation, ultraviolet radiation, and other types. These different forms of radiation are distinguished based on what property? Sunlight is a mixture of electromagnetic waves, ranging from infrared to ultraviolet.
Explanation:
The Kinetic Energy Formula is as follows: KE = mass x velocity^2 /2
Plug in the correct numbers into the variables!
KE = 1500 kg x 10 m/s ^2 / 2
Square the 10 m/s!
KE = 1500 kg x 100 m/s / 2
Multiply!
KE = 150,000 / 2
Divide!
KE = 75,000 Newton-meters or Joules!
