• 4.9m/s
• 9.8m/s
• 19.6m/s
• 29.4m/s

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

An object is shot from the ground (at 25 m/s) at 25 degrees and 65 degrees.  Which one rises to a higher height? (assume no air resistance)

• 25 degrees
• 65 degrees
• same for both

An object is shot from the ground (at 25 m/s) at 25 degrees and 65 degrees.  Which one has the greater range?   (assume no air resistance)

• 25 degrees
• 65 degrees
• same for both

Which angle will produce the greatest range (in the absence of air resistance)?

• 0 degrees
• 45 degrees
• 90 degrees
• none of these

Two balls of the same mass begin at a height of 2m. One is released from rest while the other begins with a horizontal velocity of 5m/s. Which object its the ground first?

• Ball A
• Ball B
• Both balls his the ground at the same time
• unable to determine with information given

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

Two objects of the same mass are launched from the ground. Object A has a launch angle of 45, while Object B has a launch angle of 65. Which object has the greatest maximum height height?

• A
• B
• Both objects reach the maximum height
• unable to determine with the given information

Which does NOT involve acceleration?

• Coming to a stop
• Moving at a constant speed in a circle
• Moving at a constant speed in a straight line
• Speeding up from rest

When velocity is positive and acceleration is positive, what happens to the object's motion?

• The object slows down.
• The object speeds up.
• The object remains at rest.
• Nothing happens to the object.
