If we dropped a 45 N ball and a 90 N ball off of the school at the same time from the same height which one would hit the ground first? (Ignore Air Resistance)
45 N ball
90 N ball
Both will hit at the same time
Not enough information to answer the question
Terminal velocity occurs when:
the air resistance on an object increases.
an object starts to slow down due to air resistance.
the acceleration due to gravity equals zero.
the force of gravity is balanced by the air resistance on an object.

66.84 m/s
62.8 m/s
68.2 m/s
Not enough information
The two spheres in the illustration below were dropped at the exact same time and are falling through the Earth's atmosphere. Sphere A, because of its size, reaches terminal velocity, while Sphere B doesn't reach terminal velocity. Which sphere will hit the ground first?
Sphere A
Sphere B
Neither
