- a) A person is riding on a Ferris wheel of radius R. He starts at the lowest point of the wheel. When the wheel makes one complete revolution, is the net work done by the gravitational force positive, zero or negative? Do you need to know how the speed of the person changed before you can answer the question? b) Suppose the person started at the highest point of the wheel. What is the net work done by the gravitational force when he reaches the lowest point?arrow_forwardA satellite's orbit around Mars is circular. Which of the following best describes the work Mars does on the satellite? Choose 1 answer: The work Mars does on the satellite is equal to the product of the gravitational force and the circumference of the orbit. Mars does no work on the satellite because the gravitational force is perpendicular to the velocity of the satellite as it orbits Mars. The work Mars does on the satellite causes it to accelerate and gain kinetic energy. The work Mars does on the satellite is positive for one half of the orbit and negative for the other half.arrow_forwardThe figure shows four particles, each of mass 40.0 g, that form a square with an edge length of d=0.700 m.

- PHYS 111 W24: Tutorial Quiz #6 Problem 1: A skier of mass 70 kg if pulled up a slope by a motor-driven cable. (a) How much work is required to pull him 60 m up a 30 degree slope (frictionless) at a constant speed of 2 m/s? (b) What power must a motor have to perform this task? Problem 2: Three ice skaters meet at the center of a rink and each stands at rest facing the center, within arm's reach of the other two. On a signal, each skater pushes themselves away from the other two across the frictionless ice. After the push, Skater A with mass 80 kg moves in the negative y-direction at 3.5 m/s and skater B with mass 75 kg moves in the negative x-direction at 4 m/s. Find the x- and y-components of the 90 kg Skater C's velocity after the push. Assume a birds-eye view of the situation for your coordinates.arrow_forwardConsider a satellite in a circular orbit above Earth’s surface. In Chapter we will learn that the force of gravity changes only the direction of motion of a satellite in circular motion (and keeps it in a circle); it does NOT change the satellite’s speed. Work done on the satellite by the gravitational force is zero. What is your explanation?arrow_forwardThe three spheres in the figure, with masses mA = 75 g, mB = 9 g, and mc = 23 g, have their centers on a common line, with L = 23 cm and d = 4 cm.
