Arocket car accelerates uniformly from rest at and reaches maximum velocity of 150 m/s through a distance of 510 m, the boosters turn off and the rocket coasts to a stop in 22 seconds (this time is from the moment the boosters are turned off)
what is the acceleration while the boosters are on?
how far does the booster coast from the moment the boosters are turned off?
what is the average velocity of the whole trip?
