Hey
Im having some trouble with this Accelerated Linear Motion question. I don't have any clue where i should even start with part (B).
Im just lost, don't have a clue where to start. My head just starts to go into overload when i even think about it. Please help!
Im having some trouble with this Accelerated Linear Motion question. I don't have any clue where i should even start with part (B).
(A) A particle moving in a straight line with constant acceleration passes three points, p, q and r and has speeds u and 7u and p and r respecitively.
(I) Find its speed at q, the midpoint of pr, in terms o u
(II)Show that the time from p to q is twice that from q to r
(B) A juggler throws up six balls, one after the other at equal intervals of time t, each to a height of 3m. The first ball returns to his hand t seconds after the sixth was thrown up and is immediately thrown to the same height, and so on continually. You may assume that each ball moves vertically.
Find:
(i) the initial velocity of each ball
(ii) the time t
(iii) the heights of the other balls when anyone reaches the jugglers hand.
