A car with a mass of 1234 kg is traveling around a circular track with a radius of 100 m and a tangential velocity of 23 m/s. Determine the centripetal acceleration of the car.
Determine the centripetal force acting on the car.

Why is alternating current more effective at long–distance travel than direct current? a. the power lines are made out of conductors. b. transformers increase or decrease voltage as needed. c. the ac generator is more efficient. d. ac has lower voltage than dc.

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem
