A sports car starts from rest at an intersection and accelerates toward the east on a straight road at 8.0 m/s2m/s2. Just as the sports car starts to move, a bus traveling east at a constant 16 m/sm/s on the same straight road passes the sports car. When the sports car catches up with and passes the bus, how much time has elapsed?
I'm attempting to calculate acceleration for the following: A plane lands on a runway with a speed of 120 m/s, moving east, and it slows to a stop in 12.0 s. What is the magnitude and direction of the plane's average acceleration during this time interval? So far I've gotten to this point: (0m/s - 120m/s)= (-120m/s)= stuck here.. the answer must be in m/s2 (12s - 0s) (12s)
