a soccer player kicks a stationary ball giving it a speed of 20m/s at an angle of 15degrees to the horizontal. what is the maximum height reached by the ball?

Answer 1

figure the vertical component of the intial speed.

at the max height, vertical velocity is zero.

vf=0=Vi+gt where g is -9.8 find t to the highest point, then
hf=Vi*t+1/2 gt^2

Answer 2

1.5
