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.

B) Car 2 has both a larger acceleration and a larger average speed.

Explanation:

Car 2 reaches 20 m/s faster than Car 1, so it has a larger acceleration.  Car 2 also reaches point B faster than Car 1, so it has the higher average speed.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
