In this graph, time t is plotted on the horizontal anus and velocrty u on the vertical axrs. Note that by definition, velocrty and acceleration are vector quantities. ln straight-line motion, however, these vectors have only a single nonzero component in Ennt] direction of motion. Thus, in this problem, we will call u the velocity and a the acceleration, even though they are really the components of the velocity and acceleration vectors in the direction of motion_ respectively. Here is a plot of velocity versus time fora particle that travels along a straight line with a varying veloCity. Refer to this plot to answer the following questions. vx( n'ia‘s) Part A What is the initial veloCity of the particle, on? Hint A1 Initial velocity Him not displayed Howto read a vvs. tgraph ...
