Suppose the speed of a car approaching a stop sign is given by v(t) = (t - 19)2, for Osts 19, where t is measured in seconds and v(t) is measured in meters per second. a. Find v'(18) b. Interpret the physical meaning of this quantity a. v'(18)= b. Choose the correct answer below. A A. V'(18) represents the instantaneous rate of change in the car's position at t= 18 B. V (18) represents the average rate of change in the car's speed at t= 18. C. v' (18) represents the instantaneous rate of change in the car's speed at t= 18 OD. v'(18) represents the average rate of change in the car's position at t= 18. Suppose the speed of a car approaching a stop sign is given by v(t) = (t-19), for Osts 19, where t is measured a. Find v' (18) b. Interpret the physical meaning of this quantity a. v'(18)=0 b. Choose the m/s per second O A. V'(18) m/s per meter ous rate of change in the car's position at t= 18. OB. v'(18) ate of change in the car's speed at t = 18. OC. V'(18) s/m ous rate of change in the car's speed at t= 18. OD. V'(18) represents the average rate of change in the car's position at t= 18. m/s
