A space shuttle, in a 300km high orbit, releases a 100 kg payload attached by a 10 km long massless rope. Assuming initial motions of lowering payload have damped out and the shuttle and payload are flying in steady state conditions. What is the anlge of the rope as measured from a line drawn from the center of the earth through the payload? What is the tension in the rope?
A satellite is in a circular orbit about the earth (M = 5.98 x 1024kg). The period of the satellite is 3.44 x 104s. What is the speed at which the satellite travels?
A proton is suspended in a vacuum between two oppositely charged horizontal parallel plates. what is the charge of the larger sphere
How much work is required to stretch the spring. A satellite is in a low circular orbit about the Eart.
A cannon shoots a ball with an initial velocity of 152-m/s and a launch angle of 62°. The gravitational acceleration is 9.80 m/s2. Assuming no air resistance, how long would the cannonball stay in the air.
Mr. Gewanter, who's mass is 60.0 kg, is doing physics demonstration in the front of the classroom. a) How much gravitational force does he exert on 55-kg Martha in the front row, 1.50m away? b) How does this compare to what he exerts on 65-kg Lest..
