Passage / Comprehension

Two friends A and B are playing a game of collision of balls and throwing balls from the top of the tower simultaneously as shown in the figure. If the balls collide in air at point P and point O is treated as origin (g = 10 m/s^2).

Co-ordinate of the particles at point P

Options:

Answer:

Solution:

$Co-ordinate x = u cos θt \Rightarrow x = 202 \times \frac{1}{2} \times 5 \Rightarrow x = 100 and y = 300 - 202 \times \frac{1}{2} \times 5 - \frac{1}{2} \times 10 \times 25 = y = 300 - 100 - 125 = 75 Co-ordinate (100, 75)$
