A scooter goes at 36 km/h round a horizontal (unbanked) circular turn of radius 20 m. What should be the minimum friction coefficient so that it does not skid? (Take $g = 10 m / s^{2}$ )

Options:

Answer:

Solution:

$v = 36 km / h = 10 m / s, so μ = \frac{v ^{2}}{g R} = \frac{100}{10 \times 20} = 0.5.$
