+72 NEED URGENT PHYSICS HELP!
A toy brick of mass 1.5 kg slides up a 5 m ramp inclined at 30 degrees to the horizontal. The brick slows down from its initial velocity of 5 m/s as it goes, coming to a stop at the ramp. Calculate the coefficient of kinetic friction on the block.
I've been stuck on this for hours!
I tried using the kinematic equations to find the acceleration. v2^2=v1^2+2a(d)
Then with that cleared, I'm stuck on how to find the coefficient! THANKS FOR THE HELP! MUCH APPRECIATED!
