Asmall asteroid with a mass of 1200 kg moves near the earth. at a particular instant the asteroid’s velocity is ⟨ 4.30 x 104, 4.40 x 104, 0 ⟩ m/s, and its position with respect to the center of the center of the earth is ⟨ 9.00 x 106, 10.00 x 106, 0 ⟩ m. the center of the earth (mass = 5.97 x 1024 kg), is at the origin of the coordinate system. what is the (approximate) new momentum of the asteroid 2.00 x 103 seconds later?

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2

At time t=0, a particle is located at the point (3,6,9). it travels in a straight line to the point (5,2,7), has speed 8 at (3,6,9) and constant acceleration 2i−4j−2k. find an equation for the position vector of the particle.

True or false graphs must include scales that increase by the same amount
