Mass (m)=55kg
acceleration (a)=9.81 m/s^2, this is the acceleration due to gravity.
initial velocity=0m/s. The skydiver doesn’t start with any speed because she is on the plane or helicopter.
final velocity=16m/s This is the velocity (speed) the skydiver reaches
The equation we use is KE=.5mv^2
Kinetic energy=.5 mass x velocity^2
KE=.5(55kg)(16m/s)^2
KE=.5(55kg)(256m/s)
KE=.5(14080J)
J=Joules
KE=7040J
Kinetic energy is 7040 Joules (J)
Hope this helps

Answer:
An object appears white when it reflects all wavelengths and black when it absorbs them all. Red, green and blue are the additive primary colors of the color spectrum. Combining balanced amounts of red, green and blue lights also produces pure white.
Explanation:
The equation for the gravitational potential energy Ep is:
Ep=m*g*h where m is the mass of the body, g=9.81 m/s² and h is the height of the body.
First we need to find the mass of the body:
m=Ep/(g*h)=24/(9.81*3)=0.82 kg
Now lets see what it's gravitational potential energy would be on the height of 1 m.
Ep=0.82*9.81*1 = 8 J
On the height of 1 m the body has a gravitational potential energy of Ep=8 J.
