H2 Physics · JC 2 · Hard · Centripetal force
A 0.090 kg toy car moves at the top of a vertical circular track of radius 0.25 m. The normal contact force on the car at this point is equal in magnitude to its weight. Using the centripetal force equation, calculate the speed of the car at the top.
- 2.2 m s⁻¹
- 1.6 m s⁻¹
- 3.1 m s⁻¹
- 4.4 m s⁻¹
