Question

A certain light truck can go around a curve having a radius of $$150 m$$ with a maximum speed of $$32.0 m/s$$. To have the same acceleration, at what maximum speed can it go around a curve having a radius of $$75.0 m$$?


A
64m/s
loader
B
45m/s
loader
C
32m/s
loader
D
23m/s
loader
E
16m/s
loader

Solution

The correct option is D $$23m/s$$
Friction between the tires and the flat road provides the required centripetal acceleration for the truck to negotiate the curve safely without skidding.
