An object falls freely in a straight line and experiences air resistance proportional to its speed; this means its acceleration is a(t)equals minuskv(t), where k is a positive constant and v is the object's velocity. the speed of the object decreases from 1100 ft divided by s to 1000 ft divided by s over a distance of 1300 ft . approximate the time required for this deceleration to occur. hint: note that a(t)equals v prime (t ) and v(t)equals x prime (t ).
the time required for this deceleration to occur is approximately seconds. (do not round until the final answer. then round to four decimal places as needed.)
