Question

Two balls of same mass are thrown horizontally from the top of a tower in the opposite direction
with velocities 3 m/s and 4 m/s. The distance between the balls, when their velocities are mutually
perpendicular will be nearest to ?​

Answer 1

Answer:

please mark this as brain list answer....

Explanation:

v1=3i-gtj

v2=-4i-gtj

v1.v2=0 for 90 deg

=>-12+g^2t^2=0

=>gt=root12

=>t=root(12) /10

=>dis = 7 *root(12)/10
