A train begins at the origin and moves at constant speed V1 =18.2 m/s toward another train which is initially at rest at a distance d=242 m from the first train. If the second train has an acceleration of magnitude az=0.99 m/s2 toward the first train, how far does the first train move before the trains collide? (Hint: use quadratic equation and choose positive time) Select one: 245.38 m 302.01 m 75.50 m 188.76 m 132.13 m
A train begins at the origin and moves at constant speed v1=16.1 m/s toward another train which is initially at rest at a distance d=108 m from the first train. If the second train has an acceleration of magnitude a2=1.29 m/s2 toward the first train, how far does the first train move before the trains collide? (Hint : use quadratic equation and choose positive time)
A train begins at the origin and moves at constant speed v1=15.2 m/s toward another train which is initially at rest at a distance d=164 m from the first train. If the second train has an acceleration of magnitude a2=1.02 m/s2 toward the first train, how far does the first train move before the trains collide? (Hint : use quadratic equation and choose positive time)
A train begins at the origin and moves at constant speed v1=13.1 m/s toward another train which is initially at rest at a distance d=264 m from the first train. If the second train has an acceleration of magnitude a2=1.22 m/s2 toward the first train, how far does the first train move before the trains collide? (Hint : use quadratic equation and choose positive time)
A train begins at the origin and moves at constant speed v1=11.7 m/s toward another train which is initially at rest at a distance d=152 m from the first train. If the second train has an acceleration of magnitude a2=0.95 m/s2 toward the first train, how far does the first train move before the trains collide? (Hint : use quadratic equation and choose positive time)
A train begins at the origin and moves at constant speed v1=17.8 m/s toward another train which is initially at rest at a distance d=232 m from the first train. If the second train has an acceleration of magnitude a2=0.86 m/s2 toward the first train, how far does the first train move before the trains collide? (Hint : use quadratic equation and choose positive time) Select one: 74.15 m 296.59 m 129.76 m 185.37 m 240.98 m
A train begins at the origin and moves at constant speed Vi=10.7 m/s toward another train which is initially at rest at a distance d=168 m from the first train. If the second train has an acceleration of magnitude a2=1.04 m/s2 toward the first train, how far does the first train move before the trains collide? (Hint: use quadratic equation and choose positive time) Select one: O 78.06 m O 111.52 m 44.61 m O 144.97 m O 178.43 m
A train has a constant acceleration of a = 3 m/s^2 and starts 2 sec before another train that is 100 meters away from it. The other train moves in the same direction at 6 m/s. How long before the trains collide?
Two trains on separate tracks move toward one another. Train 1 has a speed of 110 km/h, train 2 a speed of 85.0 km/h. Train 2 blows its horn, emitting a frequency of 500 Hz. What is the frequency heard by the engineer on train 1? (Assume the speed of sound is 345 m/s.)
Two soccer players start from rest, 36 m apart. They run directly toward each other, both players accelerating. The first player’s acceleration has a magnitude of 0.55 m/s2. The second player’s acceleration has a magnitude of 0.41 m/s2. (a) How much time passes before the players collide? (b) At the instant they collide, how far has the first player run?
