A particle moves in XY plane according to the relations x=k t and y=k t(1-p t) where k and p are positive constants and t is time. Therefore,The velocity of a projectile at the highest point of its trajectory is 0.4 of its velocity at a point at half its maximum height. The angle of projection isA projectile is fired from ground with velocity u at an angle with the horizontal. It would be moving perpendicular to its initial direction of projection after a time t equal toA shot is fired at an angle to the horizontal up a hill (Considered to be a long straight incline plane) of inclination to the horizontal. It will strike the hill horizontally ifA ball is projected from horizontal ground. It attains a maximum height H on its projectile path and there after strikes a stationary smooth vertical wall and falls on ground vertiA particle starting from rest at the highest point slides down the outside of a smooth vertical circular track of radius 0.3 m . When it leaves the track its vertical fall is h andTwo balls are projected from the top of a cliff with equal initial speed u . One starts at angle above the horizontal while the other starts at angle below. Difference in their ran Full Motion in Two Dimensions list All Olympiad workbook PYQs
