so i thought the work done by friction would equal (16.6)(9.8)(0.181)(39.1) since friction = mu Fn and W = Fd. My second attempt, which i only tried because the first was wrong, factored out the vertical component of the pulling force when finding the normal and friction. Physics ...
When I work the problem I get 0.152 Joules. .8 = 1/2 a(2.0)^2 a=0.4 v=0.4(0.5) v=0.2 1/2(7.6kg)(.2^2)= 0.152J. I work it this way and I have no idea why it is wrong. The answer is supposed to be 0.0973. Last edited: Dec 7, 2015 Physics news on Phys.org New...

The amount of work done upon an object depends upon the amount of force (F) causing the work, the displacement (d) experienced by the object during the work, and the angle (theta) between the force and the displacement vectors. The equation for work is .
Instead, we should apply physics to the real world and use a different set of objects that we have control over, following the laws of quantum mechanics. In this first blog post, Oxford Instruments Managing Director, Stuart Woods, looks at the classical computer vs. the quantum computer and ...
High School Physics Skills Practice 1. When a boy kicks an object, it does 39.2 J of work in 10 seconds. Calculate the power of the boy on the object. 2. Determine the power generated by the turbine if it produces 3500 J of work in 10 seconds. ...

We use the ideas of a million black holes, at the boundary ofcontribution to the shift from Pre-Planckian to Planckian physics, as a summed up contribution from one million primordial black holes.I.e.this is assuming a quantum bounce.This is an extension of work done by the author as to...
