Circular Motion Quiz 2

A car moves with a constant speed of 17 m/s on a circular track of 200 m radius. Calculate the acceleration of the vehicle. HINT: a = V² / R

• 1.45 m/s²

• 0.76 m/s²

• 1.98 m/s²

• 2.34 m/s²

A 250 kg motorcycle goes around a 20.0 m radius turn at 19.0 m/s. What is the centripetal force on the motorcycle? HINT: f = MV² / R

• 2396.6 N

• 4512.5 N

• 5006.8 N

• 5656.7 N

The _______________________ supplies the centripetal force requirement for the car to move in a horizontal circle. Without it, the car would turn its wheels but would not move in a circle (as is the case on an icy surface).

• centrifugal force

• normal force

• applied force
