Two trains, traveling toward one another on a straight track, are 325 m apart when the engineers on both trains become aware of the impending collision and hit their brakes. The eastbound train, initially moving at 101 km/h, slows down at 3.40 m/s². The westbound train, initially moving at 118 km/h, slows down at 4.80 m/s². Will the trains stop before colliding? If the trains stop before colliding, what is the distance d separating them once they stop? If the trains do not stop before colliding, what initial separation d would have been needed to avert a disaster?

A red train traveling at 72 km/h and a green train traveling at 144 km/h are headed toward each other along a straight, level track.When they are 950 m apart, each engineer sees the other’s train and applies the brakes.The brakes slow each train at the rate of 1.0 m/s2. Is there a collision? If so, answer yes and give the speed of the red train and the speed of the green train at impact, respectively. If not, answer no and give the separation between the trains when they stop
Two locomotives 70 kilometers apart are travelling on the same track towards each other, Engine A moves at 22 kilometers per hour east and engine B moves at 13 kilometersper hour west. At the instant both trains begin moving, an annoying mutant fly beginsflying from engine A towards engine B at 33 kilometers per hour . The instant it touchesB, it turns around and flies back. It goes on this way until the two locomotives collideand the mutant fly is finally squashed. So, before its untimely demise, a) what is the total distance the fly flew? b) the time it took till it was eliminated and c) the average velocity of the fly? how can i find this please
A landscape architect is planning an artificial waterfall in a city park. Water flowing at 1.70 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.35 m high, and from there it will fall into a pool (Fig. P3.42). (a) Will the space behind the waterfall be wide enough for a pedestrian walkway? (b) To sell her plan to the city council, the architect wants to build a model to standard scale, which is one-twelfth actual size. How fast should the water flow in the channel in the model?

You go watch your friend as she runs at a cross country meet. The first time she passes you, your friend runs by going due north at a speed of 4.40 m/s. You move to a different place on the course and twelve minutes after you saw her the first time, your friend runs past you again. This time she is traveling at a speed of 3.80 m/s in the direction 30.0◦ W of S. What is the direction of her average acceleration between those same two times?
Suppose a car manufacturer tested its cars for front-end collisions by hauling them up on a crane and dropping them from a certain height. What height corresponds to a collision at 55 km/hkm/h ? Express your answer to two significant figures and include the appropriate units. What height corresponds to a collision at 110 km/hkm/h ? Express your answer to two significant figures and include the appropriate units.
Could someone please explain? Thank you.
1. Arthur and Betty start walking toward each other when they are 100. m apart. Arthur has a speed of 3.0 m/s and Betty has a speed of 2.0 m/s. Their dog, Spot, starts by Arthur's side at the same time and runs back and forth between them at 5.0 m/s. By the time Arthur and Betty meet, what distance has Spot run?
24. Two trains are accidentally put on the same track so that they are on a head-on collision course. Train-A is moving at 28 m/s and can decelerate at -4 m/s2. Train-B is moving at 30 m/s and can decelerate at -5 m/s2. When the trains are 190 meters apart they spot each other and immediately apply their brakes. Do they collide?
A microorganism swimming through water at a speed of 150 \mu m/s suddenly stops swimming. Its speed drops to 75 \mu m/s in 1.3 ms. What is the total distance in \mu m it travels while stopping? Express your answer in micrometers
A red train traveling at 72 km/h and a green train traveling at 144 km/h are headed toward each other on a straight, level track. When they are 950 m apart, each engineer sees the other's train and applies the breaks. The brakes slow each train at the rate of 1.0 m/s^2. Is there a collision? If so, what is the speed of the red train and the speed of the green train? If not, what is the separation between the trains when they stop?
Two trains, traveling toward one another on a straight track, are 400m apart when the engineers on both trains become aware of the impending collision and hit their brakes. The eastbound train, initially moving at 99.0km/hr slows down at 3.40 m/s^2. The westbound train, initially moving at 124 km/hr, slows down at 4.20 m/s^2. Will the trains stop before colliding?
You are standing next to an old well. You want to know how far down the surface of the water is (you are very thirsty), so you hold a rock above the well and drop it. You measure the amount of time between when you release the rock and when you year the splash produced when the stone hits the water at the bottom of the well to be T. You know that the speed of sound in air is vº and the acceleration due to gravity is g. Neglecting air resistance, find the depth of the well.
