Q)
(chatquestion)...Question 9
Two particles, 1 and 2 moves with constant velocity V1 and V2. At the initial moment their radius vectors are equal to r and
ř2 ř = 31 + 23
ř2 = 4i + 23 v1 = i + }
v2 = ki +j For particle to collide k =
only for k=1
only for k=2
for k=1 and 2 both
for all k E R (any real k)
