A car of 1500kg tied to the rope of 7m whose other end is located at the center, if the car is moving at the rate of 5m/s, calculate the centripetal force acting on it.

Sagot :

Use the formula for centripetal force F = mv²/R:
    Where F = centripetal force in Newtons
              m = mass in  kg.
              v = velocity in m/s
              R = radius in meters
 So we will have:
          
              F = 1500(5)²/7
                 = 1500(25) / 7
                 = 37500 / 7
                 = 5357.143 Newtons
              F = 5.36 kN answer..
