Question

Two spheres a and b, where A has twice the mass of B, are projected at the same horizontal velocity off the edge of two different height shelves. Sphere A leaves from a height of 2 m. Sphere B leaves from a shelf of 1.0m off the floor.

Which Ball will be in the air for a greater amount of time?

a) Ball A
b) Ball B
c) Same Time
d) there's not enough info to decide

Answer 1

a) Ball A

Step-by-step explanation:

Regardless of the mass of the ball, both balls will experience the same downward acceleration due to gravity. This means that the ball that must cover a greater distance will be in the air for a greater amount of time. Ball A falls from a height of 2 meters, while B only falls from a height of 1 meter.
