Kevin decides to soup up his car by replacing the car's wheels with ones that have 1.1 times the diameter of the original wheels. Note that the speedometer in a car is calibrated based on the tire's diameter and on the distance the tire covers in each revolution.   (a)Will the reading of the speedometer change? Yes/No      (b)If you answered 'Yes' in part (a), determine the factor by which the reading of the speedometer changes. (Enter 'NA' if you did not answer 'Yes' in part (a).) vnew vold=

A Ferris wheel rotating at 25 rad/s slows down with a constant rate of magnitude 3.7 rad/s2. How many revolutions does it make before coming to a stop? Express your answer to 1 decimal place.

A bicycle is turned upside down while its owner repairs a flat tire on the rear wheel. A friend spins the front wheel, of radius 0.408 m, and observes that drops of water fly off tangentially in an upward direction when the drops are at the same level as the center of the wheel. She measures the height reached by drops moving vertically (see figure below). A drop that breaks loose from the tire on one turn rises h = 54.3 cm above the tangent point. A drop that breaks loose on the next turn rises 51.0 cm above the tangent point. The height to which the drops rise decreases because the angular speed of the wheel decreases. From this information, determine the magnitude of the average angular acceleration of the wheel. rad/s2 h

An electric fan rotates at the rate of 850 rev / min when it is turned off. After turning off, it spins 1350 revolutions before stopping. How long did it take for the fan to stop completely?

A wheel starts from rest with a constant acceleration. It completes one complete revolution in 5 seconds. After how much time (after being started) will it complete 7 revolutions.

A rotating flywheel rotates at 400 revolutions in the first minute. In the next minute, it rotates 240 revolutions. If the number of revolutions decreases as a constant rate, how many revolutions will the wheel make before coming to a rest?

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

A small single-cylinder engine was operated on a test stand for 16 min. It was run first at 850 rpm and was then increased to 1,250 rpm. A total of 17,200 revolutions were counted during the test. How long (in min) was the engine operated at each speed?
