A blue sphere and a red sphere with the same diameter are released from rest at the top of a ramp. The red sphere takes a longer time to reach the bottom of the ramp. The spheres are then rolled off a horizontal table at the same time with the same speed and fall freely to the floor. Which sphere reaches the floor first?

The red sphere

Answer

Neither; the spheres reach the floor at the same time.

When the blue and red spheres are rolling off the horizontal table, they both have the same initial horizontal speed, and they fall under the influence of gravity. The time it takes for an object to fall to the ground depends only on the height from which it falls and the acceleration due to gravity. Assuming that both spheres are at the same height when they leave the table, they will experience the same vertical motion and therefore will hit the ground simultaneously.
