Two-wheeler can tilt while turning. But four-wheeler cannot. Estimate maximum safe speed of a four-wheeler on turn of radius 10m assuming coefficient of static friction between tires and the flat road to be 0.64 and acceleration due to gravity to be 10 `m//s^(2)` .
A
6.4 m/s
B
2.8 m/s
C
8 m/s
D
10 m/s
Text Solution
