Atrain leaves the station heading south on the tracks. it takes 5 seconds to reach 50 miles per hour. it completes the entire 100 mile trip in 2 hours. calculate the trains average speed and velocity over the two hour trip. show your work. identify each of the measurements are a ascalr or vector.

What is the momentum of a 2 kg object moving at 15 meters per second

Acar traveling at 22 m/s starts to decelerate steadily. it comes to a complete stop in 15 seconds. what is it’s acceleration?

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
