Answer:


Explanation:
t = Time taken = 0.46
u = Initial velocity
v = Final velocity
s = Displacement = 1 m
a = Acceleration

The acceleration due to gravity is 9.45179 m/s²

The function is 
Answer:
The initial speed of the ball was 26.2 m/s
Explanation:
When the football player is in the air at his maximum height the vertical component of velocity is zero, To obtain the horizontal velocity when the player catches the ball we need to apply the linear momentum conservation theorem:

we need to obtain the time taken to go down.

We have a horizontal displacement and the time taken to stop, so:

so:

Answer:
true
Explanation:
because the bonds in that element can only be shared but not transferred , but sometimes it depends on the element
