Answer 1

Answer:

sorry I don't know

Explanation:

please mark as a brilliant answer

Answer 2

Let a projectile move with a velocity u which is inclined with the horizontal at angle of θ. The velocity after time 't' will be

v=v

x

i

+v

y

j

v=ucosθ

i

+(usinθ−gt)

j

(Since:v

y

=usinθ−gt)

At maximum height the projectile will only have horizontal component that is

v

=ucosθ
