The engineer of a passenger train traveling at 25.0m/s sights a freight train whose caboose is 200m ahead on the same track. The freight train is traveling at 15.0 m/sin the same direction as the passenger train. The engineer of the passenger train immediatly applies the brakes causing a constant acceleration of .100m/s^2 in adirection opposite to the trains velocity, while the freight train continues with constant speed. will there be a collision?

When a high-speed passenger train traveling at vP = 158 km/h rounds a bend, the engineer is shocked to see that a locomotive has improperly entered onto the track from a siding and is a distance D = 692 m ahead (see the figure). The locomotive is moving at vL = 30 km/h. The engineer of the passenger train immediately applies the brakes. Assume that an x axis extends in the direction of motion. What must be the constant acceleration...

Problem 2.62 Constants The engineer of a passenger train traveling at 25.0 m/s sights a freight train whose caboose is 200 m ahead on the same track. The freight train is traveling at 15.0 m/s in the same direction as the passenger train. The engineer of the passenger train immediately applies the brakes, causing a constant acceleration of-0.100 m/s2, while the...

A train is traveling down a straight track at 33 m/s when the engineer applies the brakes, resulting in an acceleration of -1.0 m/s2 as long as the train is in motion. How far does the train move during a 66-s time interval starting at the instant the brakes are applied? Enter a number swer is not zero. m Need Help? Read

A passenger is running at his maximum velocity of 8 m/s to catch a train. When he is a distance d from the nearest entry to the train, the train starts from rest with a constant acceleration a= 1.0 m/s^2 away from him. a. If d= 30 m and the passenger keeps running, will he be able to jump on the train? b. What is the critical separation d_c such that the passenger just catches the train? c. What is...

1. A train is traveling down a straight track at 20 m/s when the engineer applies the brakes, resulting in an acceleration of 21.0 m/s2 as long as the train is in motion. How far does the train move during a 40-s time interval starting at the instant the brakes are applied? 2.A balli thrown vertically upward with a speed of 25.0 m/s.(o) How high does it rise?

Two trains are traveling on the same track and in the same direction. The first train, which is behind the second train, blows a horn whose frequency is 266 Hz. The second train detects a frequency of 284 Hz. If the speed of the second train is 13.8 m/s, what is the speed of the first train?

A driver is traveling at 30.0 m>s when he sees a moose crossing the road 80.0 m ahead. The moose becomes distracted and stops in the middle of the road. If the driver of the car slams on the brakes, what is the minimum constant acceleration he must undergo to stop short of the moose and avert an accident?

Solve the following using the 5-step process. The speed of a freight train is 75 mph slower than the speed of a passenger train. The freight train travels 340 miles in the same time that it takes the passenger train to travel 490 miles. Find the speed of each train. Instructions: Enter your answer as a whole number, fraction, or radical. When entering units, type without capitals e.g. mph, feet, meters, yards, etc. The freight train is travelling at Number...

A railroad freight car weighing 28000 kg and traveling at 6.0 m/s overtakes one weighing 19000 kg and traveling at 4.0 m/s in the same direction. If the cars couple together, find (a) the speed of the cars after collision and (b) the loss of kinetic energy during collision. (c) Is this collision elastic or inelastic? Please explain the steps. Thank you!
