An object in motion produces the velocity-versus-time graph shown. Rank in order, from largest to smallest, the accelerations a_A, a_B and a_C at points A, B and C.

• a_A > a_B > a_C

• a_C > a_A > a_B

• a_C > a_B > a_A

• a_B > a_A > a_C

The slope at a point on a position-versus-time graph of an object is

• the object’s speed at that point.

• the object’s average velocity at that point.

• the object’s instantaneous velocity at that point.

• the object’s acceleration at that point.

• the distance traveled by the object to that point.

The area under a velocity-versus-time graph of an object is

• the object’s speed at that point.

• the object’s acceleration at that point.

• the distance traveled by the object.

• the displacement of the object.

At the turning point of an object,

• the instantaneous velocity is zero.

• the acceleration is zero.

• Both A and B.

• Neither A nor B.
