Alanding craft with mass 1.21×104 kg is in a circular orbit a distance 5.90×105 m above the surface of a planet. the period of the orbit is 5900 s . the astronauts in the lander measure the diameter of the planet to be 9.80×106 m . the lander sets down at the north pole of the planet.
what is the weight of an astronaut of mass 84.6 kg as he steps out onto the planet's surface?

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?
