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

What effect does the mass of a projectile have on the time it's in the air? (Neglecting air resistance)

• The lighter the projectile, the greater the time in the air

• The heavier the projectile, the greater the time in the air

• It has no effect

• The lighter the projectile, the less the time in the air

Two objects - one with mass m and the other with mass 2m - are released from rest at the same height. Which object hits the ground first?

• mass m
• mass 2m
• both objects hit the ground at the same time
• unable to determine with information given
