A car starts 200 m west of the town square and moves with a constant velocity of 15 m/s toward the east.

a.Write the equation that represents the motion of the car.

b.Where will the car be 10 minutes later?
c.When will the car reach the town square?

  • physics -

    if the town square is at x = 0 and east is positive then:
    x = -200 + 15 t
    in ten minutes x = -200 + 150 = -50 or 50 meters west of the square
    when is x = 0?
    0 = -200 + 15 t
    t = 200/15 = 13 1/3 seconds to the square
