- In a game of freeze, a person freezes into a position shown below. As a percentage of total body mass, the head is 10%, the two arms are 10%, the trunk is 46%, and the two legs are 34%. The center of mass for each segment is given as an (x,y) coordinate, both units in cm: head = (130, 150),arms = (110, 75),trunk = (65, 95), andlegs = (0, 35). Assume the body mass for the individual is 75 kg and their total height is 160 cm. The length of the feet is roughly 10 cm. Determine the x and y-coordinates of the person's center of mass for this pose. Show all steps. Show the location of the center of mass on the diagram. Is this pose stable or unstable? Explain.Four point masses are arranged in a square of side length L as shown. All of the masses are in the xy-plane. Mass 2 and Mass 4 have mass of 4.6 kg, and Mass 1 and Mass 3 have a mass of 1 kg. If the side length L is 2.5 m, find the KE of the system if the point masses are rotated as a system around the y-axis (through m1 and m2) at 2.6 rad/sec.Sphere A of mass 0.9 kg travels with an initial velocity vA =11 m/s as shown and strikes the 2.8-kg sphere B which travels with a velocity VB =6 m/s. If the coefficient of restitution is 0.4, determine the speed of sphere B after impact. Give your answer in m/s. VA VB A B

(a) Find the total mechanical energy Е+ ЕÅ of the two satellites + Earth system before the collision. (b) If the collision is completely inelastic so that the wreckage remains as one piece of tangled material (mass = 2m), find the total mechanical energy immediately after the collision. (c) Just after the collision, is the wreckage falling directly toward Earth's center or orbiting around Earth? (a) Number Units (b) Number (c) Units A B EarthInside the Apollo spacecraft was the Eagle lunar module, which was used to that astronauts could travel to the lunar surface while the rest of the ship orbited the moon. Upon its return from the moon, the Eagle module reached a speed of 24 m/s at 305 m height. If the total mass was 10.821 kg. What was the force exerted by the ascent motor?
- QIIII: A thin uniform rod of mass Mr and length L is suspended from the ceiling and mounted on a horizontal frictionless axle at the top. The rod is initially at rest in its equilibrium position when a ball of play dough, of mass mb, strikes the rod at its lower end and remains stuck to the rod. The sticky ball is thrown with an initial speed v0 at a 60 degree angle from the horizontal direction, and strikes the rod when it reaches the top of its trajectory, as shown in Fig.4. The acceleration due to gravity has magnitude g and air resistance is negligible. a. Determine the velocity of the ball of play dough right before it sticks to the rod. Use the x- y coordinate system defined in Fig.4. b. Determine the angular velocity of the rod+ball system right after the collision. Take counterclockwise as positive. c. - Establish the differential equation satisfied by the rod+ball system after the collision and determine the angular frequency of the system.
