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?

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).

(c) 1. Speed of brett=√(5) 2. Speed ofJorden=√2.

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

A tourist is driving a car along a straight road at a constant speed of 22.5 m/s. Just as she passes a law officer parked along the side of the road, the officer starts to accelerate 2.50 m/s2 to overtake her. Assume that the officer maintains this acceleration. (a) Determine the time it takes the officer to reach the tourist (in s). 18 s (b) Find the speed of the officer as he overtakes the tourist (in m/s). 45 m/s...

1. If you are driving 85 km/h along a straight road and you look to the side for 2.0s, how far do you travel during this inattentive period? Assume that your speed remains constant. 2. A child, who is 46 m from the bank of a river, is being carried helplessly downstream by the river's swift current of 1.5 m/s. As the child passes a lifeguard on the river's bank, the lifeguard starts swimming in a straight line (perpendicular to...

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...

You are driving along straight road. You cover 200 miles in 4 hours? Does that mean that your speedometer read 50 mph for your entire trip? Is is necessary that your speedometer register 50 mph at least once during the trip? Use math to explain your answer. I understand that your speedometer would not be 50mph for the entire trip, but I am not sure how to explain it using math.
