A stationary ball is let go from the top of a 75 cm long
diagonal table. It rolls down and off the edge, free falls and hits
the ground.
a) If it takes the ball 0,797 seconds to roll down the table
before it goes off the edge, what is it's average speed?
b) What is the balls speed when it goes off the edge? Formula for
even acceleration is Vm = (V0+V)/2
c) What is the horizontal speed of the ball and what is the
horizontal speed of the ball when it falls of the edge? The height
difference is shown in the picture (24cm)
d) For how long is the ball falling, if the floor is 95cm from the
edge?
e) How far from the edge horizontally, does the ball land on the
floor?

3. Imagine a projectile is launche d horizontally and falls to the floor-say a small ball that rolls off the edge of a table. Suppose you measure two distances: the vertical distance h through which the ball fell .e., from the table down to the floor below it the horizontal distance d the ball traveled - i.e., from the point on the floor directly below the table edge to the point on the floor where the ball landed. How can...

A ball of mass m rolls horizontally off a table with speed v0, and lands a horizontal distance L from the base of the table. Suppose a ball with double the mass (2m) is rolled off the table with the same speed v0. Find an expression for the horizontal distance from the base of the table that this heavier ball lands in terms of L and any other necessary constants and variables.
