Determine the force of gravitational attraction between the earth (m = 5.98 x 1024 kg) and a 65-kg physics student if the student is in an airplane at 40000 feet above earth's surface. This would place the student a distance of 6.39 x 106 m from earth's center.
2) After using your DVD player to watch a movie, you pressed the “stop” button, and the disc started to slow down. Initially, the disc is rotating at 30.0 rad/s, and then slos down at a constant rate of 10.0 rad/s². At the same time, line AB on the disc is at the x-axis as shown in the figure. (a) What is the angular velocity of the disc at t = 0.400 s? (b) Find the angle that line AB makes with the x-axis at the given time.
A 55 kg gymmast suspends herself from the lower end of a hanging rope of negligible mass. The upper end of the rope is attached to the gymnasium ceiling (a) What is the gymnast weight? (b) What is the tension at the top of the rope?
