Question

A juggler throws a bowling pin straight up in the air. After the pin leaves his hand and while it is in the air, which statement(s) is (are) true? (Select all that apply.) The acceleration of the pin is zero. The velocity of the pin is in the same direction as its acceleration on the way up. The velocity of the pin is opposite its acceleration on the way up. The velocity of the pin is never in the same direction as its acceleration. The velocity of the pin is always in the same direction as its acceleration. When applying the equations of kinematics for an object moving in one dimension, which of the following statements must be true? (Select all that apply.) The acceleration of the object must remain constant. The velocity of the object must increase with time. The velocity of the object must always be in the same direction as its acceleration. The position of the object must increase with time. The velocity of the object must remain constant.

Explanation / Answer

1) The velocity of the pin is opposite its acceleartion on the way up,

becaue as object is goes up its acceleration due to gravity will be acting in downward direction.

2)To use the kinematic equations the acceleration of the object must be remains constant.
