4. In order for an aircraft to achieve orbit it must maintain an acceleration of 29.3 m/s^2 when considering air resistant and thrust. Karencia designs a space shuttle
that when launched will travel the 35,000,000 meters required to reach orbit in
28.15 minutes. Will her rocket achieve orbit? Why or why not? (Give numeric
evidence to support your answer)

You are driving to the grocery store at 20 m/s. you are 110m from an intersection when the traffic light turns red. assume that your reaction time is 0.50s and that your car brakes with constant acceleration. how far are you from the intersection when you begin to apply the brakes? what acceleration will bring you to rest right at the intersection? how long does it take you to stop after the light changes? the known values: vi=20m/s xi=110m t=.50s vf=0m/s xf=0m a=?
