Aferris wheel of radius 100 feet is rotating at a constant angular speed ï rad/sec counterclockwise. using a stopwatch, the rider finds it takes 5 seconds to go from the lowest point on the ride to a point q, which is level with the top of a 44 ft pole. assume the lowest point of the ride is 3 feet above ground level.

answer: f

explanation: g

Alkaline earth metals are found in group 2 of the periodic table.

Refer to the figure shown below.

From the geometry,

y = 100 - (44 - 3) = 59 ft

From the Pythagorean theorem,

x² = 100² - 59² = 6519

x = 8007403 ft

Calculate the central angle, θ.

cos θ = 59/100 = 0.59

θ = 53.84° = 0.9397 radians

Calculate the arc length pq.

S = pq = 0.9394*100 = 93.94 ft

Calculate the angular velocity.

ω = (0.9397 radians)/(5 s) = 0.188 rad/s

Calculate the tangential velocity.

v = (100 ft)*(0.188 rad/s) = 18.8 ft/s

Calculate the time for 1 revolution.

T = (2π rad)/(0.188 rad/s) = 33.4 s

Answers:

The angular speed is 0.188 rad/s

The tangential speed is 18.8 ft/s

The time for one revolution is 33.4 s
