3 A ball was launched with V=30m/s and 45 degrees to horizon from the ground. It bounces at point A on the ground and losses its vertical speed vi=rt(3)vf. The ball flies off and bounces off point B.
a) What is the distance from point A to point B?
b) To maximize the distance from A to B, what should be the initial angle?
c) What is the ratio of the displacement from origin to point A and from A to B?
d) How far the ball traveled from origin to point A and from A to B?

Best ResponseYou've already chosen the best response.0What is meant by 'losses its vertical speed'. If it has no more vertical speed it should just slide along the ground...

Best ResponseYou've already chosen the best response.0What is that vi=rt(3)vf supposed to mean anyway?

Best ResponseYou've already chosen the best response.0vi is the initial velocity and vf is the final velocity

Best ResponseYou've already chosen the best response.0and rt(3) is just an arbitrary fraction of 1?

Best ResponseYou've already chosen the best response.0okay you know that\[v _{i} = 30. \] you know that it was launched at 45 degrees. find out the horizontal and vertical components of Vi
