The diagram shows a motion map for a train.
A motion map. The position line is a long black arrow pointing right that is labeled x. Above the line are three dots with a vector pointing away from x that start farther right from x. There are three black dots that are in a vertical column above the point of the third vector. There are two yellow vectors with no black dots pointed toward x starting just above the vertical column of three dots.
Which statement is supported by the motion map?
The train traveled south and then north.
The train moved at a velocity of 75 mph north.
The train had a greater velocity when it moved away from the origin.
The train stopped for 3 seconds.

3. a particle with initial velocity v⃗ 0=(5.85×103m/s)j^ enters a region of uniform electric and magnetic fields. the magnetic field in the region is b⃗ =−(1.35t)k^. you can ignore the weight of the particle. a. calculate the magnitude of the electric field in the region if the particle is to pass through undeflected, for a particle of charge +0.640 nc.
