Question

A) At the local swimming hole, a favorite trick is to run horizontally off a cliff that is 6.91 m above the water. One diver runs off the edge of the cliff, tucks into a "ball," and rotates on the way down with an average angular speed of 1.62 rev/s. Ignore air resistance and determine the number of revolutions she makes while on the way down. B) Two people start at the same place and walk around a circular lake in opposite directions. One has an angular speed of 1.59 x 10-3 rad/s, while the other has an angular speed of 5.03 x 10-3 rad/s. How long will it be before they meet?

Step 1

We want to find the number of revolutions, which is the same as the number of complete circles, so we need to convert the angular speed from rev/s to rad/s: ω = 1.62 rev/s x 2π rad/rev = 10.18 rad/s Now we can plug in the values and solve for θ: θ = ωt θ = Show more…
