physics

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 487 m in 216 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.

  1. (a) 487/216 = 2.255 m/s
    (That's pretty slow!)

    (b) Vfinal/2 * 216 = 487
    Vfinal = 4.509 m/s

    (c) (4.509 m/s)/216s) = 0.0209 m/s^2
