A football is kicked with a velocity of 31 m/s at an angle of 41°. What is the ball's acceleration in the vertical direction as it flies through the air?
A. O m/s2
B. 23.4 m/s?
O
-20.3 m/s2
OD. -9.8 m/s

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
