A small ball rolls horizontally off the edge of a tabletop that is 1.2 m high. It strikes the floor at a point 1.52m horizontally away from the edge of the table. a) How long is the ball in the air? b) What is the speed at the instant it leaves the table?

I don't understand which equation I would use to solve this problem.


How long does it take to fall 1.2 m?
d= 1/2 g t^2.

solve for time.

Now, that is the same time it took to go 1.52 m horizontally, solve for speed.


wow - so obvious lol, thank you bob ;)
