John has been hired to design an exciting carnival ride. Tiff, the carnival owner, has decided to create the world's greatest ferris wheel. Tiff isn't into math; she simply has a vision and has told John these constraints on her dream: (i) the wheel should rotate counterclockwise with an angular speed of a = 15 RPM; (ii) the linear speed of a rider should be 200 mph; (iii) the lowest point on the ride should be c = 3 feet above the level ground.

a) R = 186.742 ft

b) θ = 0.7854 rads

c) θ = 14.14 rads

Explanation:

Given:

- The linear tangential velocity v = 200 mph

- The angular frequency a = 15 RPM

- The distance of bottom point from ground c = 3 ft

Find:

- The radius R of the ferris wheel

-Once the wheel is built, John suggests that Tiff should take the first ride. The wheel starts turning when Tiff is at the location P, which makes an angle θ with the horizontal, as pictured. It takes her 1.5 seconds to reach the top of the ride. Find the angle θ. (Round your answer to two decimal places.)

- Poor engineering causes Tiff's seat to fly off in 9 seconds. Describe where Tiff is located (an angle description) the instant she becomes a human missile. (Give your answer as an angle measured counterclockwise from her starting point P.)

Solution:

- The relationship between linear v and rotational speed w is given by:

v = R*w

200*5280 / 60 = R*15*2*π

R = 200*5280 / 60*15*2*π

R = 186.742 ft

- the angle swept from point P to angle θ above horizontal is given in terms of angular speed:

π/2 + θ = a*2π*1.5 / 60

θ = 15*2π*1.5 / 60 - π/2

θ = 0.7854 rads

- Similarly calculate the angle θ swept entirely till 9 seconds

θ = a*2π*9 / 60

θ = 15*2π*9 / 60

θ = 14.14 rads

- The total angle swept from initial position is θ = 14.14.

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .

An athlete swings a ball, connected to the end of a chain, in a horizontal circle. the athlete is able to rotate the ball at the rate of 8.13 rev/s when the length of the chain is 0.600 m. when he increases the length to 0.900 m, he is able to rotate the ball only 6.04 rev/s. (a) which rate of rotation gives the greater speed for the ball? 6.04 rev/s 8.13 rev/s (b) what is the centripetal acceleration of the ball at 8.13 rev/s? m/s2 (c) what is the centripetal acceleration at 6.04 rev/s? m/s2
