Max. Height is basically the total vertical distance covered by the projectile.
Time of flight is the time for which projectile was in the air .
Horizontal range is the horizontal distance it has covered.
Mark as brainliest please if helpful
and angle=k from horizontalor ground of projectile
so horizontal speed of projectile=Vx=Vcosk
max ht it attained =h(say)
vertical speed= Vsink
V2-U2=2ah
0-vsink^2=2(-g)h
h=(vsink^2)/2g
v-u=at
0-vsink=(-g)t
t=vsink/g
total time projectile in air=2t=2vsink/g
horizontal range=Vcosk.2t=2v^2sinkcosk/g
=v^2sin2k/g
