Problem

Two particles

A

and

B

are projected from the same point on an inclined plane with the same initial speed

u

. Particle

A

is projected perpendicular the incline (upwards), while particle

B

is projected horizontally (down the slope). If the incline angle is

45^{\circ}

, compare the time of flight

T_{A}

and

T_{B}

for the two particles to return to the incline.
