Question

Can someone check my solution?

Answer 1

Are you noting VA as speed at A? And VB at B?

Answer 2

no, Va as my initial velocity
the Vb is the velocity when it approaches A
i treat Vb as final velocity when it arrives at A then i use it as initial velocity to solve for t

does it makes sense? O.o

Answer 3

Yeah. Kinda confusing though. I'll continue.

Answer 4

okay, maybe there's another way how to solve this .... hmm

how will you solve this kind of problem?

Answer 5

It looks right to me.

Answer 6

are you sure? O.o
did you try it?

Answer 7

Yeah. You can wait for someone else to check it too.

Answer 8

okay, ^.^
