Hi all,
First time here; I was just looking for help on a couple of Biomechanics questions I have:
1. You are moving into your new apartment and you are pushing a bookcase across a carpeted floor. The coefficient of friction between the bookcase and the floor is 0.65. What force is required to move the bookcase if its mass is 40 kg. Assume gravity equals 9.81 m/s².
2. In a Nike shoe design laboratory, the frictional properties of a shoe are being tested. The shoe is placed on a piece of board and then one end of the board is raised. The raising of the board from one end creates a slope. The board is continuously raised from one end until the shoe begins to slide down the board. For one shoe, this angle is 35º. Calculate the frictional force, the normal force and the coefficient of friction if the shoe’s mass is 200 grams. Report your answers to 2 decimal places.
3. A vertical jump is performed and the only data made available to you is the flight time of the jumper which is 0.600 s. Calculate the jump height achieved. Report your answer to 2 decimal places.
=======================================================
I don't necessarily want the answers; I'd much prefer to understand the process involved in finding the answers so I can do it myself; At this point though, I'm pretty much stumped :S
Any assistance with regards to these would be MOST greatly appreciated
Thanks again everyone:cool:
P.S. I hope I posted this in the right section :S
