A fully loaded, slow-moving freight elevator has a cab with a total mass of 1400 kg, which is required to travel upward 56 m in 4.9 min, starting and ending at rest. The elevator's counterweight has a mass of only 900 kg, so the elevator motor must help pull the cab upward. What average power is required of the force the motor exerts on the cab via the cable

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.
