Q. What minimum horsepower must a motor have to be able to drag a 320 box along a level floor at a speed of 1.10 if the coefficient of friction is 0.50?

Q. Two stationary positive point charges, charge 1 of magnitude 3.35 and charge 2 of magnitude 1.75 , are separated by a distance of 30.0 . An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges.

What is the speed of the electron when it is 10.0 from charge 1?

Express your answer in meters per second.
