Problem 1) Elon Musk has personally chosen you to travel to the newly discovered planet ice planet Hoth. Before leaving on your mission, you measure your Earth weight to be 742 N. When you land on Hoth, you weigh yourself again and find your Hoth weight to be 924 N. Part A What is the acceleration due to gravity on Hoth? Problem 1 Continued) To travel on Hoth, you will "water ski" along its flat liquid methane lakes by having a drone pull you with a rope. When the drone pulls on you via the rope with a force of magnitude 922 N at an angle of 17.0° above the horizontal, you accelerate forward at 3.14 m/s2. While you are moving, you can assume that there is a force of kinetic friction between your skis and the surface of the liquid methane lake. You can also assume that your skis maintain contact with the surface of the liquid methane lake for the entirety of your motion. Part B Draw a complete free body diagram of you when you are "water skiing" along the flat liquid methane lake. Label…

Item 12 On a Ferris wheel, at certain parts of the motion, gravity plays a role in providing the necessary radial acceleration. Specifically, at the top of the circle, gravity is pulling toward the center of motion, and at the bottom of the circle, gravity is pulling away from the center of motion. A passenger moves in a vertical circle of radius R with constant speed 2. (a) Assuming that the seat remains upright during the motion, derive expressions for the magnitude of the upward force the seat exerts on the passenger at the top and bottom of the circle if the passenger's mass is m. (b) What are these forces if the passenger's mass is 60.0 kg. the radius of the circle is R 10.00 m'and the wheel makes one revolution in 10.0 s? How do they compare with the passenger's actual weight?

Figure 1 a. Block speed (m/sec) = 0.2 x time (sec) b. Pulling force (N) = 0.2 x block mass (kg) c. Block speed (m/sec) = 5.0 x time (sec) d. Pulling force (N) = 5,0 x block mass (kg) 13. James and John dive from an overhang into the lake below. James simply drops straight down from the edge. John takes a running start and jumps with an initial horizontal velocity of 25 m/s. Compare the time it takes each to reach the lake below if there is no air resistance. * a. James reaches the surface of the lake first. b. Cannot be determined without knowing the weight of both James and John. C. John reaches the surface of the lake first. d. Cannot be determined without knowing the mass of both James and John e. James and John will reach the surface of the lake at the same time. hp
