a) 515/229
b) average speed = (0 + final speed)/2 = answer to part (a)
in other words
answer to b = twice answer to a
c) a = change in velocity/change in time
= answer to part b /229 seconds
Two cars cover the same distance in a straight line. Car A covers the distance at a constant velocity. Car B starts from rest and maintains a constant acceleration. Both cars cover a distance of 515 m in 229 s. Assume that they are moving in the +x direction. Determine (a) the constant velocity of car A, (b) the final velocity of car B, and (c) the acceleration of car B.
