Answer 1

Answer:

If the coefficient of friction between the wheels of a race car and the road is 0.2. (a) What is the optimum speed of the race car to avoid wear and tear on its tires?(b) What is the maximum permissible speed to avoid slipping? ... v2=rgtanθ. =10×300×tan15. v2=780m/s. v=28m/s. (b) Maximum permissible speed to avoid ...
