Acar of mass 800kg goes round a corner of radius 65m at a speed of 10m/s. a) what size force is needed to achieve this? b) suggest how this force is likely to be obtained. c) what force would be needed if the driver approached the bend at twice the speed?

Answer 1

a) centripetal force ... f = m v^2 / r

b) "where the rubber meets the road" ... tire friction

c) from the equation ... doubling the velocity would quadruple the force
