They share electrons because it is a covalent bond
Answer:

24.21 m/s
Explanation:
x = Displacement in x direction = 55 m
y = Displacement in x direction = 0
= Height of the ball when the ball is kicked = 1 m
t = Time taken = 4.2 s
= Acceleration due to gravity = 
u = Initial velocity of ball
Displacement in x direction is given by

Displacement in y direction is given by


The ball should be kicked at an angle of 

The initial speed of the ball is 24.21 m/s.
Heat lost = (75000)(3.77)(3) = 848250 J = heat gained by water
848250 = 400000(4.814)(T)
T = 0.507 C
4 + 0.507 = 4.507 C
