A train 350 m long is moving on a straight track with a speed of
83.9 km/h. The engineer applies the brakes at a crossing, and later
the last car passes the crossing with a speed of 15.2 km/h.
Assuming constant acceleration, determine how long the train
blocked the crossing. Disregard the width of the
crossing.

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...

A mini train is moving at a constant speed along a straight, horizontal track. The train consists of an engine, which is in front, and one car that is being towed by the engine by a cable. The engine and car are not touching. There is a coefficient of kinetic friction of between the engine and the track, and between the car and the track. The coefficient is the same for both; it is 0.100. The engine has a mass...

A car moving at 90 km/h passes a 1.21 km -long train traveling in the same direction on a track that is parallel to the road. Part A If the speed of the train is 71 km/h , how long does it take the car to pass the train? Express your answer using two significant figures. Part B How far will the car have traveled in this time? Express your answer using two significant figures. Part C If the car...

A train which is traveling at 73 mi/hr applies its brakes as it reaches point A and slows down with a constant deceleration. Its decreased velocity is observed to be 56 mi/hr as it passes a point 1/2 mi beyond A. A car moving at 36 mi/hr passes point B at the same instant that the train reaches point A. In an unwise effort to beat the train to the crossing, t the driver "steps on the gas." Calculate the...

8). (15 points) Two train cars are on a straight, horizontal track. One car starts at rest and is put in motion with a constant acceleration of 2.50 m/s2. This car moves toward a second car that is 32.0 m away. The second car is moving away from the first car and is traveling at a constant speed of 4.50 m/s. a) Where will the cars collide? b) How long will it take for the cars to collide?
