a train moving west with an initial velocity of 20 m/s accelerates at 4 m/s2 for 10 seconds. during this time, the train moves
a distance of
meters.

the area between the graph and the t axis

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

truck y has a greater velocity than truck x.

i believe the answer is a hope it and is correct
