BELKI 3. Betty (mass 40-kg), standing on a frictionless ice patch, catches her leaping dog Imass 1s-kgl which is moving directly horizontally, at 3.0 m/s. Please answer the following questions A. Compute Betty's momentum BEFORE collision with her doggie. 8. Compute the momentum of her dog BEFORE COLLISION C. Compute the direction and the speed of Betty and her dog after collision It takes Betty 0.2 s to secure the dog in her arms, compute the force with which the...

A stationary skater with a mass of 80.0 kg and a moment of inertia (about her central vertical axis) of 3.00 kg-m2 catches a baseball with her outstretched arm. The catch is made at a distance of 1.00 m from the central axis. The ball has a mass of 145 g and is traveling at 20.0 m/s before the catch. (a) What linear speed does the system (skater + ball) have after the catch? (b) What is the angular speed...

In the diagram below, a 75 kg college student is standing at the perimeter of a merry-go-round initially at rest) which can be considered a uniform solid disk with a mass of 130 kg and a radius of 2.1 m. The frictionless vertical rotation axis is indicated by the dot. A friend throws a 0.42 kg football to the person on the merry-go- round, who catches it when the part of its velocity parallel to the ground is 12 m/s...

A physics student of mass 59.0 kg is standing at the edge of the flat roof of a building, 12.0 m above the sidewalk. An unfriendly dog is running across the roof toward her. Next to her is a large wheel mounted on a horizontal axle at its center. The wheel, used to lift objects from the ground to the roof, has a light crank attached to it and a light rope wrapped around it; the free end of the...
