a. enter a symbolic expression for the average acceleration vector of the car during the given time period in terms of the problem and standard unit vectors.b. What is the magnitude, in meters per squared second, of the car's acceleration during the given time period.
After Dan makes a basket, Josephine claims she can find the amount of time the ball was in the air (from the time it leave's Dan's hand to the time it enters the basket). 10 ft Josephine says she can do this by using Dan's equation ( h (t) = - 16t2 +18t + 8) and setting the equation equal to zero. Dan doesn't think Josephine's thinking is correct. Who do you agree with? Explain your reasoning using mathematical evidence. 0/10000 Word
