Tony pulls a luggage cart at an angle of 30 degrees to the horizontal. The luggage cart has a mass of 35 kg, and he pulls with a force of 75 N. a) What is the normal force on the luggage cart?
b) What for e would Tony need to apply at a 30 degree angle to pull the luggage cart completely off the ground?
c) How does your answer in part (b) change as the angle increases?

After the near spacecraft passed mathilde, on several occasions rocket propellant was expelled to adjust the spacecraft's momentum in order to follow a path that would approach the asteroid eros, the final destination for the mission. after getting close to eros, further small adjustments made the momentum just right to give a circular orbit of radius 45 km (45 × 10^3 m) around the asteroid. so much propellant had been used that the final mass of the spacecraft while in circular orbit around eros was only 545 kg. the spacecraft took 1.04 days to make one complete circular orbit around eros. calculate what the mass of eros must be.
