Ball A is thrown vertically upwards with a velocity of v0 . Ball B is thrown upwards from the same point with the same velocity t seconds later. Part A
Determine the elapsed time t<2v0/g from the instant ball A is thrown to when the balls pass each other .
Express your answer in terms of some or all of the variables v0, t, and the acceleration due to gravity g .
1 answer:
Answer:
The answer is
Explanation:
If the ball is thrown vertically, the equation of its position is
So setting our coordinate system in the position of throwing , the equation for A is
and for B
where
due to the delay of the throwing between A and B, "t"
.
Now, the balls passing each other means that
then
cancelling some terms...
