Answer:

ANSWER

Height of projectile at its highest point is h=

2g

u

2

sin

2

θ

.

Horizontal distance covered till this point is x=

2

R

=

2g

u

sin2θ

=

g

u

2

sinθcosθ

.

Time taken to reach highest point is t=

T

=

g

usinθ

Hence, displacement is d=

h

θ

).

Average velocity v=
