At a particular moment, a spacecraft of mass 15000 kg is at location (-6.4 x 107,0,0) m relative to an origin at the center of the Earth. At this instant the momentum of the spacecraft is (0,4.9 × 107,0) kg-m/s, and the force on the spacecraft by the Earth is (1472,0,0) N. Part 1 Assuming the force on the spacecraft by the Earth is approximately constant over a 1 hour interval, what will the momentum of the spacecraft be in 1 hour? (Remember to convert Ar to seconds.)

The boy has a velocity of v = 0.38 m/s to the left. What would be the girl's velocity in this case? (Consider the ice to be frictionless. Enter the magnitude only.) Two ice skaters, a boy on the left and a girl on the right, face each other in figures a and b, which depict, respectively, before and after pushing off from each other. Before: The two ice skaters face each other with the palms of their hands facing towards each other and touching the other person's palms. After: The two ice skaters have pushed off and now have their arms outstretched facing each other. A left-pointing arrow above the left skater is labeled "v". A right-pointing arrow above the right skater is labeled "?".
- 3. (Level 1&2) A box is freely moving on a horizontal, frictionless plane when suddenly a slight push changed the motion of the box. At the instant the force is applied the momentum of the box is described by the equation: p = (-3.00kg - m/s)i + (4.00kg - m/s)j The push caused a force to act on the box for quite some time and this force is given by: F = (0.280N/8)tî + (-0.450N /s²)ť° } Calculate the momentum of the box after 2 seconds, if the impulse at t = 0 s for both x- and y- components are zero.Solve for BHelp with this homework question would be great, thanks!
