QUESTION 33 a 0. t Choose the appropriate word choices below that correctly complete the blanks in the following three sentences: At the beginning, the object is at the origin and moving to the left. In the first half of its motion, the object moves to the left with velocity. Then, the motion of the object changes. In the second half of its motion, the in magnitude. object due to a acceleration that is CA. decreasing, speeds up, negative, increasing, B. constant, speeds up, positive, constant, C. constant, slows down, positive, constant, D. increasing, speeds up, negative, increasing, E. constant, speeds up, negative, constant,

Short computation The position of an object as a function of time is given by x(t) = bt2 - ct, where b = 2.2 m/s² and c = 7.1 m/s. What is the instantaneous velocity v of the object when t = 7.9 s? v= m/s Remember to include a "-" if the velocity turns out to be negative. Do not include a "+" for a positive value. Report your numerical answer below, assuming three significant figures.

Describe a means of transportation and a point-to-point travel route with which you are familiar.  Use this route to explain the difference between and the meaning of the following terms: distance, displacement, speed, velocity, and acceleration. Do not use a path with zero displacements; for example from home to work and back home. Identify those quantities which are vectors, and which are scalars.  Give magnitudes and direction from your example route as appropriate.
