Question

A projectile is projected up an inclined plane of inclination 30° at an angle of projection 30°.
If speed of projection is 100 V3 m/s and it strikes the plane perpendicularly then time of flight is​

Answer 1

Answer:

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).
