Derive a formula for the bullet speed vvv in terms of DDD, TTT, and a measured angle θθtheta between the position of the hole in the first disk and that of the hole in the second. If required, use ππpi, not its numeric equivalent. Both of the holes lie at the same radial distance from the shaft. θθtheta measures the angular displacement between the two holes; for instance, θ=0θ=0 means that the holes are in a line and θ=πθ=π means that when one hole is up, the other is down. Assume that the bullet must travel through the set of disks within a single revolution.

before we can answer, we have to see the choices that are printed there with the question.   that's the only way we can point you to the correct one.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
