	The angular speed of a wheel		2020-09-03
		Catrina pose la question : A car is moving at a rate of 75 miles per hour, and the diameter of its wheels is 2.6 in. Find the angular speed of the wheels in radians per minute. Penny Nom lui répond.
	Angular velocity		2018-12-05
		Kolade pose la question : Krusty the Clown and Sideshow Bob have covered themselves in velcro, and shot themselves out of a large cannon so that they stick to a huge rotating velcro wheel (don’t try this at home). As shown in Figure 1(a), Krusty is now stuck to a point 3.00 m from the center of the wheel while Bob is stuck to another point 5.00 m from the center. The wheel is rotating counterclockwise at 10.0 rpm. Conveniently a set of axes is suspended just in front the wheel (Krusty asked for axes, like the ones you would use to chop wood, so that he and Bob could chase each other with them in the usual wholesome entertainment he is known for. Unfortunately, the set designer misunderstood.) The axes do not rotate with the wheel. (a) Find Krusty’s and Bob’s angular velocities, in radians per second. Penny Nom lui répond.

		Akidima pose la question : A bicycle wheel rotates uniformly through 2.0 revolutions in 4.0 seconds . What is the average angular speed of the wheel Penny Nom lui répond.
	Angular speed		2017-01-21
		Kenzi pose la question : A wheel of radius 14 inches is rotating 45°/sec. What is the linear speed in in/sec and the angular speed in RPM? (Round your answers to three decimal places) I already found the linear speed. I got 10.996 in/sec. I don't know how to find the angular speed. Penny Nom lui répond.

		Edward pose la question : Hello; I have a 28.2 inch diameter tire; do not worry about engine RPM or gear ratios, please tell me what the RPM of that tire is at 8 MPH and 64 MPH. Thank you. Sincerely; Edward Penny Nom lui répond.
	Angular speed		2014-06-29
		andrea pose la question : a wheel having a radius of 10cm rotates such that the linear speed at its rim is 30mls. what is the angular speed of the wheel in rpm? Penny Nom lui répond.
	Angular velocity		2012-09-05
		Kyra pose la question : A belt connects a pulley of radius 8cm to a pulley of radius 6cm. Each point on the belt is travelling at 24 cm/sec. Find the angular velocity of each pulley. Penny Nom lui répond.
	Angular speed		2010-12-03
		Julie pose la question : If the angular speed of a circle is 360 degrees divided by the time it took to rotate, how do I calculate ones that have greater rotations than the amount of time? I mean, you calculate the angular speed of a merry-go-around that spins once every 5 seconds by doing 360degrees/5 sec, but how do you calculate a merry-go-around that has 16 rotations every 4 seconds? Penny Nom lui répond.

		Lindsay pose la question : Determine the angular velocity, in radians per second, of a 14-inch car wheel, if the car is traveling at 60 miles per hour Harley Weston lui répond.
	A dead fly is stuck to a belt that passes over two pulleys		2009-03-21
		Jules pose la question : A dead fly is stuck to a belt that passes over two pulleys 6 inches and 8 inches in radius. Assuming no slippage,how fast is the fly moving when the large pulley (8 inches) makes 21 revolutions per second ? How many revolutions per second does the small pulley make ? How long will it take the dead fly to travel 1 mile ? Penny Nom lui répond.

		Rebecca pose la question : A point on a belt is moving at the rate of 30 ft/sec and the belt drives a pulley at the rate of 200 rpm. What is the radius of the pulley? Penny Nom lui répond.
	The current in a river		2008-06-12
		Joi pose la question : To approximate the speed of the current of a river, a circular paddle wheel with radius 4 feet is lowered into the water. If the current causes the wheel to rotate at a speed of 10 revolutions per minute, what is the speed of the current? Express your answer in miles per hour. Harley Weston lui répond.
