Relative speed of Tina with respect to David is given by
now the acceleration of Tina with respect to David
now the relative displacement would be zero when Tina cross David
so now we have
now the speed of Tina at this moment is given as
<em>so the speed will be 52 m/s</em>
Answer:Impossible to answer without knowing their actual initial speeds
Explanation:
Given
Ball A launched at angle of
Ball B is launched at angle of
At the highest point Ball vertical velocity will be and there will be only horizontal velocity i.e. and
where is the velocity of A & B
thus to find which one is greater we need to know their initial velocity.
It is impossible to know which one have higher velocity at highest point.
