Unformatted text preview: astronaut at a velocity of ( 1.35 3.64 ) m/s. Find the (vector) velocity of the first astronaut after she threw the module. 5. [10 points] Calculate the velocity required for a satellite of mass 675 kg to be in a circular orbit that is 3473 km above the surface of the earth. (The other data you need are on the front page of the exam.) 6. [20 points] Given that = ( 51.4 + 32.2 ) N and = ( 24.1 + 13.4 ) N act on a 5.67 kg mass that is initially moving at = ( 9.87 7.44 ) m/s, (A) calculate the acceleration of the mass (B) calculate the time when the x component of its velocity is zero. 7. [15 points] A wind-up toy car with a mass of 1.39 kg is released from the top of a ramp that is 0.876 m high. It rolls down the ramp and across a carpeted floor, stopping after traveling 2.68 m. If there is a 9.89 N force of friction from the carpet, how much work was done by the windup motor in the car?...
