A player kicks the football from the ground with a velocity of of 30m/s at 45 degree angle. The time take to reach maximum height was 0.7 s. Find the maximum height and describe your work.
but vf in the vertical is zero at the top, so
solve ford Vi
Height= vivertical*t-1/2 g t^2
= Vi*sin45*t-1/2 g t^2
