Question1

A certain elevator cab in a New York hotel has a total run of 178 m. Its greatest speed is 251 m/min. Its acceleration (both speeding up and slowing down) has a magnitude of 1.14 m/s2.

How long does it take to create the nonstop 178 m run, starting and ending at rest?

Question2

Two stationary positive point charges, charge 1 of magnitude 4.00{rm nC} and charge 2 of magnitude 1.70{rm nC}, are unconnected by a distance of 46.0{rm cm}. An electron is free from rest at the point midway between two charges, and it moves all along the line linking the two charges.

Question3

Two point charges and are held in place 4.50 apart. One more point charge -2.30 of mass 6.00 is at first located 3.00 from each of these charges and free from rest. You study that the initial acceleration of -2.30 is 334 upward, parallel to the line linking the two point charges.
