Question

a particle is projected with a velocity of 30m/sec at an angle 60°above the horizontal on a slope of inclination 30° find its range, time of flight​

Answer 1

Answer:

change the frame of reference along the slope.

acc due to gravity will now have two components.

apply NLM v = u + at to get time of flight.

and ut - 0.5 at*t to get the range.

compare the final velocities to get the angle of hit wrt to slope and add the slope angle to get the absolute angle of hit.
