How did u measure the distance? you used a ruler right? So I measured the horz distance with a ruler and I got 3.2cm which is 0.032m.
im nt sure of dat value bt u mst first measure da vertical distance frm ruler x to y den use da distance calc in prev question to make a scale den convert da horizontal measurement into da real horizontal distance
dat da time taken fr half da motion of da projectile u must multiply dat by 2
I assume we were told only to deal with the falling distance just (x to y) ..not like like that of the ball going up and then coming down so were not required to find the time of flight or something..

O yeah i did like that..what did u get as horz distance?
Did any1 else get 7.9x10^-14 ohm metres for the resistivity on the last q?
And did any1 get 0.77 for the efficiency of the electric motor q? The current and voltage were given along with the mass and height the weight was lifted by...

No because we gave unit 1 IAL,You're on the wrong thread dude.
