Question

(#1) A small block with 2 kg of mass moves up the inside wall of a large circular pipe. The pipe has a radius of 3 meters, and the coefficient of kinetic friction between the pipe and the block is 0.2. If at this moment, the speed of the block is 4 m/s, moving up the wall, and 0 = 34° determine: (a.) The normal force the pipe exerts on the block (b.) The tangential acceleration at point (c.) The total acceleration at this point. sm kg Un=0.2

Answer 1

Solution, 2 kg) MK = 0.2, m= R=3m v= 4 m/s and o=34" mu2 R HN N= mgcose + muz R masina (a) at given point, along Normal N-mg esse = ngease mgcoso N = 2x9.8 x cos 34°+ 2X4X4 mg 3 N= 26.916 N un fretrós force Fret force along the downward Ft = mysing- + UN 2x9.8X SIN 34+2x 26.916 Ft= 64.79178 N tangential acceleration at = Ft = 32.395 m/s2 at= (32.395 m/s2 (Direction down the (c) tangent) centripetal acceleration 1 = 42 = (16) m/s² Net acceleration m ас: anet = račtat anet 1077.938 anet = (32.8319 m/s² = 32.8319 mis?
