Q. How high a tree would a 80.0 kg person have to climb to increase his gravitational potential energy relative to the ground by that amount?

Q. A proton accelerates from rest in a uniform electric field of 660 N/C. at one later moment, its speed is 1.60 Mm/s (nonrelativistic because v is much less than the speed of light).

a. find the acceleration of the proton

b. over what time interval does the proton reach this speed?

c. how far does it move in this time interval?

d. what is its kinetic energy at the end of this interval?
