You are driving your car (let’s define the direction you are traveling in as positive) at 25.0 m/s. A van is following 150.0 m behind you, also traveling at 25.0 m/s. At time t = 0.0 s you see a fog bank ahead, and you hit the brakes. The van driver applies her brakes two second later, at t = 2.0 s. Both vehicles have a constant acceleration of a = -5.0 m/s2 while braking. Each vehicle eventually comes to a complete stop. Draw the graph.

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.
