At time t = 0 a car has a velocity of 16 m/s. it slows down with an acceleration given by –0.50t, in m/s^2 for t in seconds. by the time it stops it has traveled: a) 15 m b) 31 m c) 62 m d) 85 m e) 100 m

The car's velocity at time is

It comes to rest at

Its velocity over this period is positive, so that the total distance the car travels is

so the answer is D.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
