239.Brett and Jordan are out driving in the coordinate plane, each on a separate straight road. The equations Bt = (−3, 4) + t[1, 2] and Jt = (5, 2) + t[−1, 1] describe their respective travels, where t is the number of minutes after noon. (a) Make a sketch of the two roads, with arrows to indicate direction of travel. (b) Where do the two roads intersect? (c) How fast is Brett going? How fast is Jordan going? (d) Do they collide? If not, who gets to the intersection first?

Solutions

Expert Solution

(a)- Different paths only intersects at one point only as in sketch.

(b) intersection of roads occurs at point (x,y)=(-1,8).

(d) they doesn't collide each other, Brett intersects first at t=3min on y axis.

Consider driving a car in one direction along a straight road for 10 minutes. You start from rest. During the first 1 minute, you speed up with constant acceleration until you reach 60 m/s. During the next 5 minutes, you maintain constant speed at 60 m/s. During the final 4 minutes, you have constant negative acceleration (i.e. deceleration) until you are not moving. How far in total did you travel during the whole 10 minutes? Express your answer in units...
