An object is projected horizontally from a cliff.  The time it takes to hit the ground is

• more than if it was just dropped
• less than if it was just dropped
• the same amount of time than if it was just dropped
• impossible to determine

An object is shot from the ground (at 25 m/s) at 25 degrees and 65 degrees.  Which is in the air for longer? (assume no air resistance)

• 25 degrees
• 65 degrees
• same for both
