so here i am doing my physics homework. everythings fine, but then i get this whopper of a problem, which is for major marks, and i cant seem to solve it for some reason. here she is: a ramp is setup on the edge of a table a ball slides down this ramp and picks up speed. just as it leaves the ramp it hits a stationary ball, identical to the first, located at the very bottom of the ramp the two balls collide and fall a certain distance to the floor below, hitting the ground at exactly the same time. the balls land on the floor below: one of the balls lands 30cm away from the bottom of the ramp; 32 degrees to the right of ramp the other ball lands 33.25cm away from the bottom of the ramp; 43 degrees to the left of ramp some things to remember: -the height of the ramp, height of the table, time, weight/size of the balls are unknown, but constant -a single ball going down the same ramp lands 47.6 cm away from the bottom of the ramp. prove in the most efficient way that momentum is conserved.
