A 35-kg child is traveling a 2.50 m/s when she enters the final section of the Giant Waterslide. That section is 5.0 m long and has a vertical drop of 4.0 m. The force of friction opposing the child's motion is 40.0 N. Determine the (a) loss of potential energy and (b) work done by friction in the this final section. c) Use the work energy principle to determine the child's velocity at the end of the section.

Intro: a solid ball of radius rb has a uniform charge density ρ. part a: what is the magnitude of the electric field e(r) at a distance r> rb from the center of the ball? express your answer in terms of ρ, rb, r, and ϵ0. part b: what is the magnitude of the electric field e(r) at a distance r express your answer in terms of ρ, rb, r, and ϵ0. part c: let e(r) represent the electric field due to the charged ball throughout all of space. which of the following statements about the electric field are true? check all that apply. e(0) = 0 e(rb)=0 limr→∞e(r)=0 the maximum electric field occurs when r=0 the maximum electric field occurs when r=rb the maximum electric field occurs as r→∞.
