An artillery shell is fired 1.75m above the ground at a 30.0° angle and an initial velocity of 625 m/s. Assume no air resistance. a. What is the vertical component of the shell’s muzzle velocity?

b. What is the horizontal component of the shell’s muzzle velocity?

c. What was the shell’s maximum height?

d. How long until the shell reaches its peak (maximum height)?

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.
