A red train traveling at 20 m/s and a green train traveling at 40 m/s are headed toward one another along a straight, level track. When they are 950 m apart, each engineer sees the other's train and applies the breaks. The breaks decelerates each train at the rate of 1 m/s˄2. What is the speed (in m/s) of the green train at impact?

As a science project, you drop a watermelon off the top of the Empire State Building, 320 m above the sidewalk. It so happens that Superman flies by at the instant you release the watermelon. Superman is headed straight down with a speed of 37.0 m/sm/s.How fast is the watermelon going when it passes Superman?
A cat is sleeping on the floor in the middle of a 3.0 m wide room when a barking dog enters with a speed of 1.50 m/s. As the dog enters, the cat immediately accelerates at 0.85 m/s2 toward an open window on the opposite side of the room. The dog is a bit startled by the cat and begins to slow down at 0.10 m/s2 as soon as it enters the room. How far is the cat in front of the dog as it leaps through the window?
Two cars are moving towards an intersection. One car is 150 meters north of the intersection and moving towards the intersection at 20 m/s, while the other is 180 meters west of the intersection and moving towards the intersection at 16 m/s. How rapidly are the cars approaching each other 4 seconds later?
9. A tourist being chased by an angry bear is running in a straight line toward his car at a speed of 4.0 m/s. The car is a distance d away. The bear is 26 m behind the tourist and running at 6.0 m/s. The tourist reaches the car safely. What is the maximum possible value for d?
Car A was traveling east at high speed when it collided at point O with car B , which was traveling north at 45 mi/h. Car C , which was traveling west at 60 mi/h, was 32 ft east and 10 ft north of point O at the time of the collision. Because the pavement was wet, the driver of car C could not prevent his car from sliding into the other two cars, and the three cars, stuck together, kept sliding until they hit the utility pole p. Knowing that the weights of cars A, B, and C are, respectively, 3000 lb, 2600 lb, and 2400 lb, and neglecting the forces exerted on the cars by the wet pavement, solve the problems indicated.Knowing that the coordinates of the utility pole are xp= 46 ft and yp = 59 ft, determine (a) the time elapsed from the first collision to the stop at P,(b) the speed of car A.
two friend 50m apart are walking towards each other in a straight road. Man A is walking at a speed of 0.25m/s while the Man B is walking at 0.8m/s. If a pigeon above man A flies towards man B at a constant speed of 5 m/s and flies back again to man A when it is above man B. This goes on until two friends meet. Assuming that there is no speed loss every time the pigeon changes its direction. Determine the total distance that the pigeon flew?
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?
Moving sidewalks are installed every other 50 meters along the entire stretch of an airport walkway. These sidewalks move at a constant speed of 1 m/s. A lady passenger takes one of the sidewalks to go from one point to the next. If the passenger decides to go back using the same sidewalk at 1 m/s, how long will it take to reach her point of origin?
Two stones are separated by a vertical distance y (in meters) from each other. One stone is thrown down with an initial velocity v01 = -23 m/s and the other is thrown up from the ground with an initial v02 = 8 m/s at the same time the other is thrown. How far, in meters, must they be separated so they hit the ground at the same time? What is the impact velocity, in meters per second, of the first stone? What is the impact velocity, in meters per second, of the second stone?
A man who is on top of a roof of a high building drops a piece of metallic material. A second piece of metallic material is dropped 3.0 seconds later. How far apart (km) are the materials when the second material has reached a speed of 15.0 m/s
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 cars approach a street corner at right angles to each other. One is red and one is blue. Both cars have the same speed of 40 km/hr. The blue car is moving due south and the red car is moving east. What is the velocity of the red car as seen by the observer in the blue car (find both the magnitude and the direction)?
