Homework Answers
Out of given options, option (d) is correct for sure.
The speed of train A is constant as slope is constant, the speed of train B is increasing as slope is positive. so option (C) is also fine.

Two trains face each other on adjacent tracks. They are
initially at rest, and their front ends are 49 m apart. The train
on the left accelerates rightward at 0.87 m/s2. The
train on the right accelerates leftward at 0.8
m/s2.

2. Two trains each moving with a constant velocity approach each other along a straight line. At a certain moment a man on the platform finds that the distance between the two trains is L and the two trains are going to collide with each other in a time 5L/7c. On the other hand another observer on one of the train sees the other train approaching him with a velocity 35cl37....

The position of two particles, A and B. are given in the x versus t graph. Assume the particles move along tracks that are placed side-by-side. At t = 0 s particle B (indicated by dashed line) is 5 m ahead of A. During the time interval shown, is there another instant when this is true? If your answer is yes, state the approximate time when this occurs. If your answer is no. state that explicitly. In either case, explain...

1. The figure below shows the first and last frames of the motion diagrams for two cars, A and B, moving in parallel straight lines. Car A travels at a constant speed, while car B is continuously speeding up. B a. Complete the motion diagrams of both cars. Be sure to use the appropriate number of dots corresponding to equal time intervals. b. Draw an appropriate coordinate axis underneath the motion diagrams. We'll use the same axis for both cars....

An object is moving along a straight line in the positive x direction. The graph shows its position from the starting point as a function of time. Various segments of the graph are identified by the letters A, B, C, and D. a. Describe what the object is doing during each segment of the trip. Calculate all constant variables. b. What is the average velocity for the trip.
