Question

.) Find an expression of maximum range up an incline for a given
projectile.
[2]​

Answer 1

Explanation:

Maximum range up the inclined plane,

(Rmax)up=g(1+sinα)u2

Maximum range down the inclined plane

(Rmax)down=g(1−sinαu2)

and according to :g(1−sinα)u2=3×g(1+sinα)u2

By solving α=30o
