Given the following situation of a ball in motion on a rail with negligible Ftriction: a. Sketch a motion map showing the motion of the ball after it leaves the rail, using the grid to help you carefully locate the marble's positions. Show both horizontal and vertical velocity vectors on each dot. \_I~ I ... - I I -- ...... " "-r-.. "' "- "' \ (~ >to · 4 c: ot ' r 4-,f..i b. Describe how you will determine the velocity of the ball right before it falls off the table. This needs to be completed without the ball falling off the table. ~/Q v {-e-t 19 1--- i '1 e ,t'yt. 1 , o r1 -i ht r.r~ 1 fJ\. 1 1 r 1 -< T { df j ( 'h i ~ 11 J or.: ·c{'le ~"l' k•v l11t.vr 1"' "1f'11,f- oi 1J "ll , 17 (> vtrt.J o c- <i~r::f i--> .... _:,,,-? ,,11,/1.+ ')C>flf~r 't11Qt1_ 1,eq ( ... ov -c1J1 i t~-e ft -rt1A..f\.
