A soccer ball is kicked at an angle of 15 degrees with the ball traveling at 15.0 m/s

a) what is the max height reached by the ball?

b) max range?

c) how could range be increased?

so i need to find:

y_{max}

R = x_{max}

2. Relevant equations

these i assume are the given:

[tex]\vartheta[/tex]=15 degrees

v_{0}=15.0 m/s

a_{y}= -g

x_{0}, y_{0}and y = 0

3. The attempt at a solution

vx_{0}= v_{0}cos 15 = 15 cos 15 = 14.5

vy_{0}= v_{0}sin 15 = 15 sin 15 = 3.88

v_{y}= 0 = v_{y}- gt_{u}<---t_{u}is time of ball movin upward

must get t_{u}:

= v_{y0}/ (g)

here is where i get stuck cuz i dont know what to do with the g since i dont have a value for it.
