a train has an initial velocity of 30 m/s. If the train accelerates uniformly at a rate of 6.3 m/s ^ for 2.8 seconds what is the trains final velocity?

T

the velocity is a second final to initial velocity of 39

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

so easy. just google the electromagnetic waves and it’ll pop up.
