acceleration4. An object has negative velocity and positive

accelerationA.2 OnlyB.4 OnlyC. 2 and 3 OnlyD.1 and 4 OnlyE. All are possible

Which of the Following Have a Positive Acceleration?

1. Speeding up while moving in the + direction2. Slowing down while moving in the + direction3. Slowing down while moving in the - direction4. Speeding up while moving in the - direction

A.1 and 4 OnlyB.1 OnlyC.4 OnlyD.1 and 3 Only

Which of the Following Have a Zero Acceleration?

1. Airplane flying level due east at a constant 500 mph

2. Child on a spinning merry-go-round3. Ball thrown straight up at its highest point4. Ball reversing direction after rolling up a ramp

A.1 OnlyB.1 and 2 OnlyC.1, 3 and 4 OnlyD.1 and 3 Only

A Ball is Given a + Initial Velocity and then Rolls up a Ramp as Shown Below

What will happen to its Velocity and Acceleration as it Rolls up the Ramp?

A.V Decreases, A IncreasesB.V Decreases, A DecreasesC.V Decreases, A ConstantD.V Constant, A Constant

+

The Ball Continues up the Ramp and Reaches Its

Highest Point

What is the Ball’s Acceleration at this Point?

A.ZeroB.Smaller than Before, but not zeroC.Same as Before, but changes signD.Same as Before

+

The Ball is Now Rolling Back Down the Ramp

What will happen to its Velocity and Acceleration as it Rolls Down the Ramp?

A.V Increases, A IncreasesB.V Increases, A DecreasesC.V Decreases, A ConstantD.V Constant, A Constant
