A wheel with a tire mounted on it rotates at a constant rate of 2.89 times a second. A tack is stuck in the tire at a distance 39.1cm from the rotation axis. noting that for every rotation the tack travels one circumference. find the tacks tangential speed.
m/s
what is the tacks radial acceleration?
m/s^2

(A) Tangential speed will be equal to 7.09 m/sec

(B) Radial acceleration will be equal to  

Explanation:

We have given angular speed of the wheel

Radius of the track r = 39.1 cm = 0.391 m

(A) Tangential speed will be equal to , here is angular speed and r is radius

So tangential speed

So tangential speed will be equal to 7.09 m/sec

(B) Radial acceleration will be equal to

So radial acceleration will be equal to

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

the answer is mosques. they are an important part of islamic culture.
