Question

r Medical 2 e ual same time 9. 2166. Two projectiles projected horizontally at time from a height in opposite directions are 40 m apart when these are moving at right angle to one another. Then their separation when their position vectors are at right angle
​

Answer 1

Answer:

v1=u1i^−gtj^

v2=−u2i^−gtj^

forv1⊥v2

vˉ1.vˉ2=0

(u1i^−gtj^).(−u2i^−gtj^)=0

−u1u2+g2t2=0

g2t2=u1u2

t=gu1u2
