Find the angular speed v for the hour hand of a clock
A Ferris wheel has a 116-foot diameter and the center of the Ferris wheel is 62 feet above the ground. The Ferris wheel rotates in the CCW
direction at a constant angular speed of 5 radians per minute. Jacob boards the Ferris wheel at the 3-o'clock position and rides the Ferris wheel for
many rotations. Let t represent the number of minutes since the ride started.
a. Write an expression (in terms of t) to represent the number of radians Jacob has swept out from the 3-o'clock position since the ride started.

The angular speed is radian per hr.arrow_forwardDavid boards a Ferris wheel at the 3-o'clock position and rides the Ferris wheel for multiple revolutions. The Ferris wheel rotates at a constant angular speed of 6.2 radians per minute and has a radius of 30 feet. The center of the Ferris wheel is 36 feet above the ground. Let t represent the number of minutes since the Ferris wheel started rotating.arrow_forward
- Crawling Researchers at the University of Denver Infant Study Center wondered whether temperature might influ-ence the age at which babies learn to crawl. Perhaps the extra clothing that babies wear in cold weather wouldrestrict movement and delay the age at which they startedcrawling. Data were collected on 208 boys and 206 girls.Parents reported the month of the baby’s birth and theage (in weeks) at which their child first crawled. Thetable gives the average Temperature (°F) when the babieswere 6 months old and average Crawling Age (in weeks)for each month of the year. Make the plots and computethe analyses necessary to answer the following questions.a) Would this association appear to be weaker, stronger,or the same if data had been plotted for individualbabies instead of using monthly averages? Explain. b) Is there evidence of an association between Tempera-ture and Crawling Age? Test an appropriate hypothesis and state your conclusion. Don’t forget to check theassumptions.c)…arrow_forwardFor an object in simple harmonic motion, the number of cycles per unit time is called the_______arrow_forwardFind the absolute value of the radian measure of the angle that the second hand of a clock moves through in the given time 35 seconds.arrow_forward
- The minute hand of a clock rotates -8 pi. How many radians does the hour hand rotate? (For every 360 degrees that the minute hand rotates, the hour hand rotates 30 degrees)arrow_forwardA point starts at the location (4, 0) and travels CCW along a circular path centered at the location (0, 0). (Draw a diagram of this!) Imagine an angle with the initial ray pointing in the 3 o'clock position with a terminal ray passing through the point. The point moves at a constant speed, and the angle sweeps out 2 radians per second. Let t represent the number of seconds since the point started moving. a. Write an expression (in terms of t) to represent the number of radians the angle has swept out since the point started moving. Preview b. Write a formula that expresses the r-coordinate of the point in terms of the number of seconds t since the point started moving. (Hint: what is the radius of the circular path?) Preview c. How long does it take the point to complete one full rotation? seconds Preview d. Sketch a graph relating z to t.
