a 275-kilogram object starts from rest and accelerates on level ground up to a speed of
41 meters per second over 49.3 meters. it continues at that speed for another 15
meters. at the end of the 15 meters, the object is launched forward at a 37° angle.
a. how much time does it take for the object to reach its final velocity?
b. how much force did the object apply in order to reach that final speed?
c. what are the maximum range and height of the object when it is launched?
d. at what angle would the object have to be launched to reach a height of 50
meters above the ground at the same initial velocity?
e. describe a realistic scenario in which this might happen.

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.
