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 player using a cue accelerates a shuffleboard disk at a constant 7.3m/s2 from rest for 0.65sec. At this point the disk loses contact with the cue and slows down at a constant rate of 2.3 m/s2 until it stops. What is the total distance traversed by the disk?
Consider a dragster that, when the light turns green, accelerates uniformly from rest and completes a 372 meter race in a time of 6.61 seconds. a) During this period, what is the dragster's acceleration expressed as a multiple of the acceleration due to gravity, g? b) If the dragster could continue with this average acceleration, what would its speed be, in miles per hour, after it has traveled a total distance of 1.6km1.6km, which is approximately one mile?
A pirate has buried his treasure on an island with five trees located at the points (30.0 m, 20.0 m), (60.0 m, 80.0 m), (10.0 m, 10.0 m), (40.0 m, 30.0 m), and (70.0 m, 60.0 m), all measured relative to some origin, as shown in Figure P1.69. His ships log instructs you to start at tree A and move toward tree B, but to cover only one-half the distance between A and B. Then move toward tree C, covering one-third the distance between your current location and C. Next move toward tree D, covering one-fourth the distance between where you are and D. Finally move toward tree E, covering one-fifth the distance between you and E, stop, and dig. (a) Assume you have correctly determined the order in which the pirate labeled the trees as A, B, C, D, and E as shown in the figure. What are the coordinates of the point where his treasure is buried? (b) What If? What if you do not really know the way the pirate labeled the trees? What would happen to the answer if you rearranged the order of the trees, for instance, to B (30 m, 20 m), A (60 m, 80 m), E (10 m, 10 m), C (40 m, 30 m), and D (70 m, 60 m)? State reasoning to show that the answer does not depend on the order in which the trees are labeled. Figure 1.69

A base ball pitcher with a 90-mi/h fastball throws a ball while standing on a railroad flatcar moving at 110 mi/h. The ball is thrown in the same direction as that of the velocity of the train.If you apply the Galilean velocity transformation equation to this situation, is the speed of the ball relative to the Earth (a)90mi/h, (b)110mi/h, (c)20mi/h, (d) 200mi/h, or (e)imposssible to determine?
Sometime in the future, we will develop a space ship which can go up to half the speed of light. On a flight to the nearest star which is 4.2 light years away, we will keep the acceleration up to one g. How long will the trip take? (The trip will have three sections, the first accelerating up to maximum speed, the second at constant speed, and the third decelerating at - g to rest at the destination.)
The distance S that an object falls varies directly with the square of the time t. If an object falls 16 feet in one second, how long for it to fall 400 feet? The time required to drive a fixed distance varies inversely as the speed. It takes 1 hr at a speed of 400 km/h to drive a fixed distance. How long will it take to drive the same distance at a speed of 8 km/h?
The Moon is about 3.8 ✕ 108 m from Earth. Traveling at the speed of light, 3.0 ✕ 108 m/s, how long does it take a laser beam to go from Earth to the Moon and back again (in s)?
You encounter a moving walkway that is 81 m long and has a speed of 2.1 m/s relative to the ground. How long would it take you to cover the 81 m length of the walkway if, once you get on the walkway, you immediately turn around and start walking in the opposite direction with a speed of 1.6 m/s relative to the walkway? Express your answer using one significant figure.
An object moving with a speed of 6.25 m/s, is decelerated at a rate givenBy dv dt= −2.5√v where v is the instantaneous speed. The time taken by the object to come torest would be.
