A red train traveling at 72 miles/hour (mph) and a green train traveling at 100 mph are headed toward one another along a straight, level track. When they are 2500 feet apart, each engineer sees the other's train and applies the brakes. The brakes decelerates each train at the rate of 2.0 meters per second squared. Is their a collision? If so, what is the speed of each train at impact? If not, what is the separation between the trains when they stop?
Give the given and solution:
A stone is thrown horizontally with a speed of 12 m/s from the edge of a 10 m high cliff. With what speed does it hit the ground? (Note: This is a two dimensional problem)
To decide who pays for lunch, a passengeron a moving train tosses a coin straight upward with an initialspeed of 5.25 m>s and catches it again when it returns to its initial level. From the point of view of the passenger, then, the coin’sinitial velocity is 15.25 m>s 2yn . The train’s velocity relative to theground is 112.1 m>s2xn . (a) What is the minimum speed of the coinrelative to the ground during its flight? At what point in the coin’sflight does this minimum speed occur? Explain. (b) Find the initial speed and direction of the coin as seen by an observer on theground. (c) Use the expression for ymax derived in Example 4-14 tocalculate the maximum height of the coin, as seen by an observeron the ground. (d) What is the maximum height of the coin fromthe point of view of the passenger, who sees only one-dimensionalmotion?

- In the absence of air resistance, if a ball is thrown vertically upward with a certain initial speed, on returning to its original level it will have the same speed. When air resistance is a factor, will the ball be moving faster, the same, or more slowly than its throwing speed when it gets back to the same level? Why? (Physicists often use a “principle of exaggeration” to help them analyze a problem. Consider the exaggerated case of a feather, not a ball, because the effect of air resistance on the feather is more pronounced and therefore easier to visualize.)arrow_forwardA projectile is fired from 3 meters height above level ground with an initial velocityequals to 20 m/s and at an angle equals to 30 degrees above the horizontal level. Notethat the air resistance is neglected. the position of a particle with respect to time is defined by:r(t) = rcos(cot )i +rsin(cot)j ,where w and r are constants.Demonstrate that the magnitude of the acceleration of the particle is constant.arrow_forwardAn airplane releases a ball as it flies parallel to the ground at a height of h as shown in the figure. If the ball lands on the ground a horizontal distance equal to the height h from the release point, find the speed v of the plane in terms of h and g. Neglect any effects due to air resistance. Note that this type of question is to be solved symbolically, ie, using only the symbols h and g, instead of plugging in numbers.arrow_forward
