In a location where the train tracks run parallel to a road, a high-speed train traveling at 100 m/s passes a car traveling at 20 m/s. How long does it take for the train to be 240 m ahead of the car?

You are driving down the highway late one night at 20 m/s when a deer steps onto the road 35m in front of you. Your reaction time before stepping on the brakes is 0.50 s , and the maximum deceleration of your car is 10 m/s2 . How much distance is between you and the deer when you come to a stop?

A horseback rider is escaping from his pursuers. He sees a way out of his quandary in crossing a railroad before a long train reaches an intersection with the highway. At the moment he is 100 meters away while the train is 200 meters from the intersection and speeding at 75 km/hr. From his current speed of 20 km/hr what should his acceleration be if he succeeds to escape?

A single-engine air plain starts its engine at one end of the runway. It accelerates at a constant rate and takes off at 38 m/s after 20 seconds on the runway, just as it is running out of runway. How long is the runway? Your Answer:

You're driving down the highway late one night at 20m/s when a deer steps onto the road 35m in front of you. Since it takes your brain and body a bit of time to react, you travel for another 0.5s at this speed before hitting the brakes. Your car's maximum braking acceleration has a magnitude of 10m/s2. How far do you travel between the instant you see the deer and the instant you come to a complete stop?

A Ford passes a Toyota on the road (both vehicles are traveling in the same direction). The Ford moves at a constant speed of 35.9 m/s. Just as the Ford passes it, the Toyota is traveling at 16.8 m/s. As soon as the Ford passes the Toyota, the Toyota begins to accelerate forward at a constant rate. Meanwhile the Ford just keeps going at a steady 35.9 m/s to the east. The Toyota catches up to the Ford a distance of 101.4 m ahead of where the Ford first passed it. What was the magnitude of the Toyota s acceleration?     6.8 m/s^2     2.5 m/s^2     13.5 m/s^2     5.0 m/s^2

You are arguing over a cell phone while trailing an unmarked police car by 27.0 m. Both your car and the police car are traveling at 100 km/h. Your argument diverts your attention from the police car for 2.30 s (long enough for you to look at the phone and yell, "I won't do that!"). At the beginning of that 2.30 s, the police officer begins emergency braking at 5.00 m/s². (a) What is the separation between the two cars when your attention finally returns? m (b) Suppose that you take another 0.400 s to realize your danger and begin braking. If you too brake at 5.00 m/s², what is your speed when you hit the police car? km/h

A Boeing 747 "Jumbo Jet" has a length of 64.5 m. The runway on which the plane lands intersects another runway. The width of the intersection is 24.8 m. The plane decelerates through the intersection at a rate of 5.56 m/s2 and clears it with a final speed of 43.1 m/s. How much time is needed for the plane to clear the intersection?

An object is thrown straight up with a speed 27 m/s from the edge of a bridge spanning a lake.  The object hits the water 6.8 s later.  How high (in meters) is the bridge above the water?

A child stands on a bridge over the highway and drops a water balloon straight downwards.The bridge is 11 m above the ground. The water balloon strikes the very front of a low-rider car that is 18 m away when the balloon is dropped.(A) How long does it take the balloon to reach the ground.(B) If the car is moving at a constant speed, how fast is the car moving.
