A1. For problem 21.57, write a formula for the position vector
of the electron as a function of time,
r⃗(t)r→(t), using unit vector ("i-hat"
and "j-hat") notation. Assume the electron starts at the origin of
your coordinate system at t = 0, so
r0→=0iˆ+0jˆ.

The figure shows a plot of potential energy U versus
position x of a 0.280 kg particle that can travel only
along an x axis under the influence of a conservative
force. The graph has these values: UA
= 9.00 J, UC = 20.0 J and
UD = 24.0 J. The particle is released
at the point where U forms a “potential hill” of “height”
UB = 12.0 J, with kinetic energy 5.00
