2) The 'plum pudding' model of the atom was used by scientists in the early part of the 20th century to explain atomic structure.
Electrons
"Pudding'
(a) Those scientists knew that atoms contained electrons and that the electrons had a
negative charge. They also knew that an atom was electrically neutral overall.
What did this allow the scientists to deduce about the 'pudding' part of the atom?

Horizontal distance can be computed using the formula:

dx = vt

Where:
dx=horizontal distance
v=velocity
t = time

Your problem gives you the velocity and time; 2 m/s and 1.7s respectively. All you need to do is fill in what you know and solve for what you don't know. 

dx=vt
dx=(2m/s)(1.7s)
dx=3.4m

The answer is then B.
