Question

for the direction of projection for the range of a projectile to be maximum on an inclined plane having angle of inclination 30 degree to the horizontal?

Answer 1

Explanation:

Range:- During time of flight, the horizontal velocity u cos α remains constant. The greatest distance of the projectile from the inclined plane is u2sin2 (α-β)/2gcosβ . A Particle is projected with a velocity 39.2 m/sec at an angle of 30o to an inclined plane (inclined at an angle of 45o to the horizontal).
