A train 500 m long is moving on a straight track with a speed of 81.0 km/h. The engineer applies the brakes at a crossing, and later the last car passes the crossing with a speed of 16.5 km/h. Assuming constant acceleration, determine how long the train blocked the crossing. Disregard the width of the crossing.

Two runners start simultaneously from the same point on a circular 200-m track and run in opposite directions. One runs at a constant speed of 6.20 m/s, and the other runs at a constant speed of 5.50 m/s. When they first meet, (a) for how long a time will they have been running, and (b) how far will each one have run along the track?
A locomotive composition, with a constant speed of 75 km/h, moves in thewestbound for fifty minutes, then in a direction that makes an angle of 25° to the west with the north direction, for 35 min and finally in the eastbound for another 40 min. Determine:(a) the module of the average composition speed, in km/h, during that journey;b) the angle of the average speed of the composition, in relation to the first direction of the trip.

Suppose you went for a drive along a long, straight road that runs east-west. Let's define east to be the positive x direction. From your home, you drive east at 30. mi/hr to your friends house for 20. minutes, then at 48 mi/hr east for 10. minutes to the grocery store. Finally, you drive west at 60. mi/hr without stopping to get home. How many minutes will it take to drive from the grocery store to your home (at 60. mi/hr)? Note: Your answer should have the correct number of significant figures
