Comprehension 1 We know how by neglecting the and analysed Now we consider the case of of collision can be simplified by considering the case of elastic collision only When a a wall we can divide its velocity into two components one perpendicular to the wall a to the wall If the collision is elastic then the perpendicular component of reversed with the same magnitude Velocity just before collision A B Vcose Vsine their motion in air is correct A H H H Vcose Vsine Components of velocity Components of velocity just after collision just before collision B H H H ball is throw stant a pers projection Yes 60 particle is p K particle ha The other parallel component of velocity will remain constant if given wall is smooth I same angle with the horizontal The balls A B and C collide with the wall during their Now let us take a problem Three balls A and B C are projected from ground with all three collide perpendicularly with the wall as shown in figure velocity The maximum height attained by ball A from the ground is A 10 m B 15 m C 20 m 17 2 ur particle i 1 y x 3 xy ca water fe v the to A proje Which of the following relation about the maximum height H of the three balls from the 1 C H H H D H H R If the time taken by the ball A to fall back on ground is 4 seconds and that by ball B is 2 the time taken by the ball C to reach the inclined plane after projection will be A 6 sec B 4 sec C 3 sec D 5 sec v g boy ca hrow th 1 20 fg 1 ya D Insufficient
