My U is .200 and I know that Ff=U * normal force. How do I find the normal force, then one I find the normal force what do I do to find the required power. I just need some steps and guidence. Thanks

I have a free body which a 140 N force going along the + x-axis a N force (normal) going + along Y axis a vector "W" in the third quad with a polar angle of 235'. What do i do next. I know that i need to find the acceleration of the block. Where and how does the coeficient of friction come...

I found the dispancement to be 122.6 m? But I do not know how to find the kinetic energy and potential energy in joules?

Homework Statement A 500N sign is dropped off a building. % seconds later it strikes the ground. Calculate the Max KE and the original PE of the sign Homework Equations The Attempt at a Solution I know I need to find at least three of these varriables Vo = 0 Vf...

Homework Statement Calculate the acceleration for a 10.0kg block which is being pulled up a 35 degree slope by a force of 140 N if the coefficient of friction is 0.100 The answer is to be in m/s2 Homework Equations Ff=UN The Attempt at a Solution I am having trouble getting...

I knowI need Ff=UN but otherwise I do not understand how to put the acceleration problem together with the friction problem or where to even start.

Hello, I am having a hard time figuring out some physics problems. The problem states. How much power is required to pull a wagon weighingi 32200N at the speed of 25.0km/hr f the coefficient of rolling resistance is 0.200? What is the kinetic energy of the wagon? ______KW ______J...
