From an inclined plane two particles are projected with same speed at same angle , one up and other down the plane as shown in figure, which of the following statements is/are correct?
1
The time of flight of each particle is the same
2
The particles will collide the plane with same speed
3
Both the particles strike the plane perpendicularly
4
The particles will collide in mid air if projected simultaneously and time of flight of each particle is less than the time of collision
Official Solution
Correct Option:
(1)
Step 1: Formula
Time of flight on an incline for 'up' is and for 'down' is . Step 2: Analysis
Substituting and , both yield . Step 3: Collision
The relative acceleration is zero, and relative velocity is directed along the line joining them, leading to a mid-air collision. Final Answer: (A)

Official Solution
Correct Option:
(3)
Step 1: Understanding the Concept:
The horizontal velocity remains constant. The vertical velocity decreases with time. When inclination is 45°, .
A ball is projected from the point O with velocity 20 m/s at an angle of 60° with horizontal. At highest point of its trajectory, it strikes a smooth plane of inclination 30° at point A. The collision is perfectly inelastic. The maximum height from the ground attained by the ball is

22.5 m
4
20.25 m
Official Solution
Correct Option:
(1)
Step 1: Understanding the Concept:
At highest point, velocity is horizontal: . In perfectly inelastic collision with incline: velocity component along the plane remains, perpendicular component becomes zero. Step 2: Detailed Explanation:
Height of highest point : . Velocity along incline after collision: . Additional height along incline: . Vertical height gained: . Total maximum height: . Step 3: Final Answer:
