A car has an initial speed of 250m/sec, the distance of the car can be modeled by the function D(t)=20t²+250t, where D(t) represents the height of the arrow (in meters) after t seconds (assume the car has a constant acceleration.) Calculate D(30) and include Units.

A car has an initial speed of 250m/sec, the distance of the car can be modeled by the function D(t)=20t²+250t, where D(t) represents the height of the arrow (in meters) after t second. Calculate When the distance is equal to zero.

a)

Distance is zero at $t=250\ s$
