Question

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.

(10%) Problem 1: A car moves along a horizontal road with constant velocity
vo
= V0,x
i
=
= (33 m/s) i
until it encounters a smooth inclined hill. It climbs the hill with constant velocity
V1 = V1,x î + V1,y Ĵ
=
(35 m/s)i + (5.8 m/s) j
as indicated in the figure. The period of time during which the car changes its velocity is
At = 1.9 s.
