Question

Two balls are thrown simultaneously A vertically upwards with a
speed of 20m/s from the ground and B vertically downward from a
height of 40 m with the same speed and along the same line of
motion at what distance do the two balls collide? How to solve this
question with the help of relative velocity}?

Dear Student,

let they collide at height xx=20t-gt2240-x=20t+gt2240-20t+gt22=20t+gt2240-20t=20t40t=40t= 1 sec
x=20-102=15 m Regards
