Two cars travel on a straight road from point a to point b. both cars accelerate to their maximum speed and then continue at that speed for the rest of the distance. car 1 accelerates from rest to 20 m/s over 30 s. it reaches point b in 35 s. car 2 accelerates from rest to 20 m/s over 20 s. it reaches point b in 30 s. which car uses a larger acceleration to reach its maximum speed, and which car has a larger average speed?
a) car 1 has both a larger acceleration and a larger average speed.
b) car 2 has both a larger acceleration and a larger average speed.
c) car 1 has a larger acceleration, but car 2 has a larger average speed.
d) car 2 has a larger acceleration, but car 1 has a larger average speed.
