Problem

Two identical inclined planes

A

and

B

have angles of

30^{\circ}

and

60^{\circ}

respectively. A projectile is launched up plane

A

with speed

u

15^{\circ}

relative to the incline. A second projectile is launched up plane

B

with the same speed

u

15^{\circ}

relative to that incline. Determine the ratio of the Range on

A

to the Range on

B

measured along the incline.
