A red train traveling at 72km/h and a green train traveling at 144km/h are headed towards each other along a straight, level track. When they are 950m apart, each engineer sees the other's train and applies the breaks. The breaks slow each train at the rate of 1.0m/s^2. is there a collision? if so, give the speed of the red train and the speed of the green train at impact, respectively. If not, give the separation between the trains when they stop.

P13 A passenger train is traveling at 29 m/s when the engineer sees a freight train 360 m ahead, traveling in the same direction on the same track. The freight train is moving at a speed of 6.0 m/s. The reaction time of the engineer is 0.40s What is the distance between the trains when the engineer applies the brakes?

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...

track, their conductors suddenly notice that they are headed toward
each other. The figure gives their velocities v as a function of
time t as the conductors slow the trains. The figure's vertical

trains are 168.00 m apart. What is their separation when both
trains have stopped?

As two trains move along a track, their conductors suddenly
notice that they are headed toward each other. The figure gives
their velocities v as a function of time t as the
conductors slow the trains. The figure's vertical scaling is set by

An automobile is traveling on a long, straight highway at a steady 75.0 mi/h when the driver sees a wreck 190 m ahead. At that instant, she applies the brakes (ignore reaction time). Between her and the wreck are two different surfaces. First there is 100 m of ice, where the deceleration is only 1.30 m/s2 . From then on, it is dry concrete, where the deceleration is a more normal 8.00 m/s2 . a). What was the car’s speed...
