Find the number of revolutions of a bicycle wheel of diameter 0.7 m When the bike goes a distance of 22 m down the street.

The tolerance is -+1 in the 3rd significant digit

Earth’s diameter is approximately 8000 miles. Estimate the speed of a point on Earth’s equator as it’s carried around with Earth’s rotation.

Two gears are connected to each other, their radius is 0.15m and 0.5m. Calculate the revolutions that the small gear completes when the big gear completes 3 revolutions

A wheel of radius 75cm is rotating with a frequency of 3.0Hz about a fixed axis of rotation. What is the speed of a piece of chewing gum stuck to the rim?

Angular speed (ω) is related to speed (v) as:  v = r × ω, where r is radius.   Determine the dimension of angular speed ω in terms of [L], [M], [T].

A physics experiment is set up using two pulleys, a string, and a weight as shown below. The larger pulley has a radius of 14 centimeters, and the smaller pulley has a radius of 8 centimeters. The distance between the centers of the pulleys is 56 centimeters. The string is pulled tightly across both pulleys so that F is a common tangent of the pulleys. Find the length of string from A to B to the nearest tenth of a centimeter. A weight O 56.0 cm O 22.0 cm O 55.7 cm O 58.5 cm

An automobile tire is rated to last for 35,000 miles. Estimate the number of revolutions the tire will make in its lifetime. O 106 revolutions O 1010 revolutions O 103 revolutions O 1012 revolutions O 107 revolutions

A bicycle initially travelling @ 4m/s accelerates @ 1.1m/s2 for 25 revolutions of each wheel. If the wheel has a radius of 0.32m, find w(angular velocity) after 25 revolutions.

A person sitting on the edge of a 1.5-m radius merry-go-round makes 18 revolutions. How far did they go linearly?
