1) A daring 51 kg swimmer dives off a cliff with a running horizontal leap. A)What must her minimum speed be just as she leaves the top of the cliff so that she will miss the ledge at the bottom, which is L = 2.40 m wide and h = 9.40 m below the top of the cliff? 2)A physics book slides off a horizontal tabletop with a speed of 3.40 m/s. It strikes the floor in 0.400 s. Ignore...

Rotational Dynamics Assignment (200 Points) • Due Friday, July 31 at 5:00 pm Equations are in a separate document entitled “Equations for Rotational Dynamics Assignment” • Moments of inertia formulas are provided on the last page of this document • Show all of your work when solving equations. It is not sufficient to merely have a correct numerical answer. You need to have used legitimate equations and algebra. You also need to...
These questions concern a space station, consisting of a long
thin uniform rod of mass 4.3 x 10^6 kg and length 769 meters, with
two identical uniform hollow spheres, each of mass 1.7 x 10^6 kg
and radius 218 meters, attached at the ends of the rod, as shown
below. Please note that none of the diagrams shown is drawn to
scale.
A. Suppose that the station starts out at rest (not rotating).
What we want is to get it...
Question 1 1 pts What is the kinetic energy of a man who weighs 980N who is riding in a car traveling 40 km per hour? Express your answer in Joules, but don't type the unit in the answer box. Round to the nearest whole number. (Careful with the units) 1 pts Astudent slides her 80.0-kg desk across the level floor of her dormitory room a distance 4.00 m at constant speed.
