Abicycle tire has a radius of 0.23 m. the tire spins at a constant speed with a centripetal acceleration of 42 m/s2. what is the tangential speed of the tire? 3.1 m/s 6.5 m/s 9.7 m/s 14 m/s

The correct answer to the question is 3.1 m/s i.e the tangential speed of the tire is 3.1 m/s.

CALCULATION:

The radius of the bicycle tire is given as r = 0.23 m.

The centripetal acceleration of the tire

We are asked to calculate the tangential speed.

Let the tangential speed is denoted as v .

The relation between centripetal acceleration, radius and tangential speed is given as -
