You take the opportunity to stock up on snacks and head on your way. You wind along the road for quite some time before you find a very dark site and pull of onto dirt road. About 100 meters up the road your passage is stopped by a metal gate. The gate consists of a single heavy bar stretching 6 meters across the road. It looks like schedule 5 stainless steel pipe, of all things, clocking in at about 7...

4.4: Problems involving Friction 4. A heavy fridge magnet is sliding down a fridge door that has a height of 67.5 cm. The magnet takes 0.92 s to slide, starting from rest, from the top of the door to the bottom. The mass of the magnet is 230 g and the magnetic force holding it to the fridge door is 2.5 N. Using this information, calculate the coefficient of kinetic friction between the magnet and the door. (Hint: start by...

1) A confined aquifer has a storativity of 0.0036. The aquifer is 64 m thick and has a porosity of 0.3300. Heavy pumping in a single well reduces the head at that point by 42 m.

questions with answers
the cylinder's vertical velocity is zero? 10. A gymnast falls from the high bar and lands on a 10 cm thick gymnastics mat. The gymnast strikes the back of his head against the mat during his landing. His head is moving at 7 m/s when it first strikes the mat. The mass of his head is 5 kg. The impact ends when the gymnast's head comes to a stop after deflecting the mat 6.5 cm. How much...

Scenario: Bart and Milhouse were at Unlucky Bar one night, drinking and watching the local scenery. Bart left Milhouse for a few moments and went to talk to some friends. The group became rather boisterous and before Bart was aware, Joe the Bouncer picked him up and threw him out the front door. Bart landed on the sidewalk and had a rather large bruise on his head and a broken arm. Questions: - What is the main legal issue, including...

In this procedure, you get to write and execute an experimental procedure to find a Thévenin equivalent model for a Light Emitting Diode (LED) The simplest model for a diode is as a switch that is on (short circuit) when current tries to flow in the direction of the arrow in the diode symbol, and off (open circuit) when the current ties to flow in the direction opposite to the arrow. This model doesn't work all that well for an...
