Question

A cyclist takes a circular turn of radius 3m at speed 18km/h on a level road. The coefficient of static friction is 0.1 will he be able to take turn.

Answer 1

Answer:

safety speed

v = √urg =√0.1×3×10 = 1.73 m/s

velocity given with which the cyclist is riding

vc = 18×5/18 = 5 m/s

since

vc > v

he wouldn't be able to take turn
