Q1. To complete your master's degree in physics, your advisor has you design a small, linear accelerator capable of emitting protons, each with a kinetic energy of 11.5 keV. (The mass of a single proton is 1.67 x 10-27 kg.) In addition, 1.00 x 10^9 protons per second must reach the target at the end of the 1.60m long accelerator.

What the average power must be delivered to the stream of protons?

Q2. A uniform plank of length 5.70 m and weight 215 N rests horizontally on two supports, with 1.1 m of the plank hanging over the right support. To what distance x can a person who weighs 452 N walk on the overhanging part of the plank before it just begins to tip?
