A small ball rolls horizontally off the edge of a table that is 1.20 m high. It strikes the floor at a point 1.52 m horizontally from the table edge. How long is the ball in the air? What is the velocity of the ball when it hits the floor?

It fell 1.20m.

1.20= 1/2 g time^2 solve for time in air.

Velocity? Its intial horizontal veloicty must have been 1.52/timeinair.

So, take the falling final velocity (v= g t), add it to the horizontal velocity as a vector at 90 degrees, and you have the velocity at the floor.

What is g? The acceleration in m/s^2?
Answered by bobpursley
g= 9.8m/s^2
