An electron and a proton are each placed at rest in an electric field of 337 N/C.
What is the velocity of the electron 57.1 ns
after being released? Consider the direction
parallel to the field to be positive. The fun-
damental charge is 1.602 x 10-19 C, the mass
of a proton is 1.67267 x 10-27 kg and of an
electron 9.109 x 10-31 kg.
Answer in units of m/s.

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
