horizontal problem:
no horizontal force so constant horizontal momentum, constant velocity u
3 meters = u t = 2 t
so t = 1.5 seconds
vertical problem:
falls h meters in 1.5 seconds with zero initial v
0 = h + 0 * 1.5 - 4.9 t^2
h = 4.9 * 2.25 = 11 meters
table is 11 meters high ? Do not sit on the edge.
(maybe 0.3 meters from the table :)
A santol rolls across a table with a speed of 2m/s and falls off the edge. If it lands 3m from the edge of the table, what height does it fall?
