Part 2<\/p>\n
Problem # 7<\/p>\n
A geostationary orbit is a circular orbit above the earth’s equator. An object in such an orbit has an orbital period equal to the earth’s rotational period, and therefore appears motionless in the sky relative to ground observers. This is useful for communication and weather satellites since antennas on earth do not have to track them and instead are pointed in a permanent direction at the orbiting satellites.<\/p>\n
Using Newton’s Law of Gravitational Attraction, a mass of earth equal to 5.9736 \u00d7 1024\u00a0kg, and an orbital period of 23 hours, 56 minutes, 4.0916 seconds, calculate the radius\u00a0R\u00a0of a geostationary orbit around the earth. (Answer: 42164 km) G = 6.673 x 10-11\u00a0N m2\/kg2<\/p>\n
Problem # 8
A block sits on an inclined plane. Draw the free-body diagram. What magnitude force do you need to push the block to prevent from sliding down? What force do you need to push to make the block start moving up the inclined?<\/p>\n
Problem # 9
Find the tension on each of the cables: Tab, Tad and Tac. Draw the free-body diagram.<\/p>\n
Problem # 10
A 2600\u00a0kg SUV traveling west at 15\u00a0m\/s collides head on with a 1300\u00a0kg sedan traveling east at 20\u00a0m\/s. Determine the speed and direction of the two cars immediately after impact if they lock together.<\/p>\n
Problem # 11<\/p>\n
Calculate the bicep tension force.<\/p>\n","protected":false},"excerpt":{"rendered":"
