Centripetal Motion

Which represents the acceleration of the ball?

• A
• B
• C
• D

Which of the following depict the tangential velocity of the ball?

• A

• B

• C

• D

Calculate the velocity of an object moved around a circle with a radius of 1.65 m and an acceleration of 3.5 m/s².

• 2.4 m/s
• 3.6 m/s
• 3.9 m/s
• 4.2 m/s

Bruno the bat flies at a speed of 0.5 m/s in circle of radius 1 m. What is his acceleration?

• 0.25 ms^-2
• 0.5 ms^-2
• 1 ms^-2
• 2 ms^-2

Centripetal acceleration always points

• in the direction of the object's motion
• in the opposite direction of the object's motion
• towards the center of the circle
• towards the outside of the circle

What is the direction of the velocity at point B, if the ball is revolving clockwise?

• up
• right
• down
• left

What's the centripetal acceleration of an object traveling 2.3 m/s around a circle of diameter 0.6 m?

• 5 m/s²

• 17.63 m/s²

• 10 m/s²

• 8.81 m/s²

What causes centripetal motion to have acceleration?

• It is speeding up

• It is slowing down

• It is changing direction
