A motorcyclist rounds a curve of radius 25 m at 36 km/h. The combined mass of the motorcycle and the man is 150 kg. 1. What is the centripetal force exerted on the motorcyclist ? 2. What is the upward force exerted on the motorcyclist? |

Answer» Data : r = 25m, v = 36 km/h = 36 × \(\frac{5}{18}\) m/s = 10 m/s, m = 150 kg, g = 10 m/s2 1. Centripetal force, F = \(\frac{mv^2}r\) = \(\frac{150\times(10)^2}{25}\) = 600 N 2. Upward force = normal reaction of the road surface = mg = 150 × 10 = 1500 N |
