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 510 m in 210 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.

a) 2.43 m/s

b) 4.83 m/s

c) 0.023 m/s²

Explanation:

a) Both cars cover a distance of 510 m in 210 s. Since car A has no acceleration

Speed = Distance / Time

Velocity of car A is 2.43 m/s

t = Time taken = 210 seconds

u = Initial velocity

v = Final velocity

s = Displacement = 510 m

a = Acceleration

c)

Acceleration of car B is 0.023 m/s²

b)

Final velocity of car B is 4.83 m/s
