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?
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
