[SOLVED] Slide, I I know I messed up on this problem somewhere, Please anybody help me figure out where. A block of mass m = 1 kg slides down an inclined plane 2 m high and 4 m long(measured alond the incline). The coefficient of kinetic friction is uk = .07. (a) What is the kinetic energy of the block when it reaches the bottom of the plane? (b) The block continues to slide over a level plane with the same value of uk. How far does it go before coming to rest? a) a = gsin(theta) theta = arcsin(2/4) = 30 degress a = (9.8)sin(30) = 4.9 m/s^2 Vf^2 = 0 + 2(4.9)(4) Vf = 6.3 m/s KE = 1/2(mVf^2) KE = 1/2(1)(6.3)^2 KE = 19.8J I can not figure out how to work in kinetic friction nor part b.
