To determine a car's maximum acceleration, you start from rest, press down hard on the accelerator pedal, and time how long it takes to get up to 26.8 m/s (about 60 miles per hour). It takes a powerful new electric car only 4.2 s to reach 26.8 m/s. What is the car's acceleration?
The car's acceleration is
m/s².

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.
