Suppose a wheel with a tire mounted on it is rotating at the constant rate of 3.37 times a second. A tack is stuck in the tire at a distance of 0.387 m from the rotation axis. Noting that for every rotation the tack travels one circumference, find the tack's tangential speed.

8.195 m/s

Explanation:

A)Period is given by: T = 1/f where f is frequency. Thus,

Period of time for 1 rev = 1/3.37 = 0.2967s

Now, velocity = distance/time

Distance will be equivalent to the circumference.

Thus,

angular Velocity= Circumference of the Circle/Time; Thus,

ω = d/t = 2πr/t

r is radius and is 0.387m

Thus,

ω = 2π x 0.387/0.2967 = 8.195 m/s

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:

frequency or wavelenth of em radiation in a vacuum
