Mechanics 1
so just when i thought i got rid of Physics.. it pops up again in one of my maths modules -___-
anywayz.. i need help with this Q about some next particle on an inclined plane...
the Q goes like this...
the answer is supposed to be 7.1 m/s^2 (2s.f) BUT like HOW??!!!!
the guy in the book drew out the question like this
thanks!
anywayz.. i need help with this Q about some next particle on an inclined plane...
the Q goes like this...
A box of mass 2Kg is pushed up a ROUGH (so friction is involved) plane by a horizontal force of magnitude 25N. The plane is inclined to the horizontal at an angle of 10 degrees. Given that the coefficient of friction ("mu") between the box and the plane is 0.3, find the acceleration of the box.
the answer is supposed to be 7.1 m/s^2 (2s.f) BUT like HOW??!!!!

Re: Mechanics 1
try gsin-ukgcos = acceleration
g = gravity (9.8m/s^2)
uk = coefficient of friction
g = gravity (9.8m/s^2)
uk = coefficient of friction

Re: Mechanics 1
sorry man i dunno ... im just a dumb noob lol ...
but it def involves trig ... too bad i never pay attention in physics lol
yeah so you know F = ma is involved too ... i feel stupid

That's easy Marwa...but to be honest I sort of forgot this and my head hurts from economics. Good Luck
But remember for slide use sin and for the other one use cos.
