Angular speed and number of revolutions per minute of a car moving at 65 mph and diameter of wheels in 2.5 feet?
There are 728.3 revolutions per minute, and the angular speed is 4576 radians per minute. This is how you get these answers: (a). Revolutions per minute. 1. Find the circumference of the circle. C= piX Diameter. In this case, C=7.8539816 2. Turn 65 mph into minutes/ft. Thus, 5280ft = 1 mile. 65X5280= 343200 ft. per hour. 1 hr = 60 minutes. 343200/60 = 5720 ft. / per minute. 3. Finally, divide. 5720/7.8539816 = 728.29 = 728.3. (b). Angular speed = central angle/time = Theta/t 1. 728.3 rpm. Now, since 1 revolution = 2pi, then, (728.3)(2pi) radians per minute. Your answer should be 4576.043859. Round to 4576 radians per minute, and you are done!!
How do you change 2 hours and 15 minutes to a fraction?
Since an hour is 60 minutes, each minute is 1/60 of an hour, and 15 minutes is 15/60 of an hour.Since an hour is 60 minutes, each minute is 1/60 of an hour, and 15 minutes is 15/60 of an hour.Since an hour is 60 minutes, each minute is 1/60 of an hour, and 15 minutes is 15/60 of an hour.Since an hour is 60 minutes, each minute is 1/60 of an hour, and 15 minutes is 15/60 of an hour.
What is half a minute as a fraction of 1 hour?
half of a sixtieth...
Lenny rode his bike to school at an average speed of 10 miles per hour what was his speed in feet per minute?
10 miles per hour is 10 times 5280 or 52800 feet per hour or 52800 / 60 or 880 feet per minute.
How convert 50 mih to feet per minute?
miles per hour x 88 = feet per minute: 50 x 88 = 4,400 feet per minute.
A wheel on a vehicle has a diameter of 36 inches If the vehicle is moving at a speed of 50 mph how many full revolutions will the wheel make in one minute?
1760 yards = 1 mile. 60 minutes = 1 hour. 36 inches = 1 yard. 50*1760 divided by 60 = 1466 yards 2 feet in one minute Circumference of wheel = pi*36 = 113.0973355 inches 113.0973355/36 = 3.141592654 yards 1466.666666/3.14192654 = 466.8048878 revolutions in one minute So the wheel makes 466 full revolutions in one minute.
How many revolutions per hour does the minute hand move on big ben clock?
The minute hand of any analog clock moves 1 revolution per hour. (60 minutes to an hour) The second hand makes 60 revolutions an hour. (Each tick represents one second, one revolution per minute, equals 60 revolutions an hour.)
How many revolutions minute hand makes in one hour?
60
What is ment by angular velocity?
It is a measure of how fast something spins, but instead of a measure in meters per second, kilometers per hour, or some similar measurement of (distance/time), a unit of rotation is used, either (angle/time) or (revolutions/time), for example radians/second, degrees/hour, revolutions/minute, etc.
How many revolutions per minute are the wheels of a bicycle turning if the diameter is 26 inches and you are traveling at a speed of 35 miles per hour?
Bicycle wheels with a diameter of 26 inches, travelling 35 miles per hour, are turning 452 revolutions per minute. 35 miles per hour is 36,960 inches per minute (25 *5280 * 12 / 60) 26 inches diameter is 81.7 inches circumference, so the revolutions per minute is 36,960 / 81.7 or 452 revolutions per minute.
A wheel with a radius of 13 meters is rotating and the outer edge is traveling at 30 miles per hour at how many revolutions per minute is its center spinning?
roughly 62 (61.897846)
If a wheel is 2 feet in diameter and does 10000 revolutions per hour how fast is it going?
A wheel 2 feet in diameter turning 10000 revolutions per hour is going, at the rim, 17.45 feet per second, or 25.6 miles per hour.
How many revolutions per minute are the wheels of a bicycle turning if the diameter is 26 inches and you are traveling at a speed of 10 miles per hour How many r?
To solve, you need how far is travelled in 1 minute and the circumference of the wheel (in the same units) which gives how far the wheel travels in one revolution; then dividing the former by the latter will give the revolutions per minute: I'll work in inches: There are 63360 inches in 1 mile and 60 minutes in 1 hour, thus: 10mph = 10 x 63360 ÷ 60 inches per minute = 10560 ipm circumference = π x diameter = 26π inches ⇒ revolutions per minute = 10560 ipm ÷ 26π ins ~= 129.3 rpm
Suppose a bike wheel has a radius of 27 inches if the bike is rolling at 10 miles per hour through what angle does spoke turn in 1 minute?
10*1760*36 = 633600 inches in 60 minutes 10560 inches in 1 minute Circumference of bike wheel = 2*pi*27 = 169.6460033 inches 10560/169.6460033 = 62.24726663 revolutions of bike wheel in 1 minute 62.24726663*360 degrees = 22409.01599 degrees in 1 minute Therefore the bike's wheel spoke has turned through an angle of 22409 degrees in I minute, correct to 5 significant figures.
How many rpm does a 18 inch dia wheel turn at 80 mph?
The circumference of an 18 inch diameter wheel is 3.14159 times 18 inches, or about 4.712 feet. 80 miles per hour is 80 times 5280 divided by 60, or about 7040 feet per minute. Divide 7040 by 4.712 and you get about 1494 revolutions per minute.
What is the velocity of a car if the wheel rotates 400 times a minute give your answer in meters per minute and kilometres per hour?
It is impossible to calculate this as we would need to know the radius of the car's wheel.
