A block accelerates at 3.1m/s2 down a plane inclined at an angle 29.0. Find k between the block and the inclined plane. The acceleration of gravity is 9.81m/s2. Solution: Fk=Frictionforceg=9.8a=3.1theta=29N=Normalforcem.a=mgsin(theta)Fkm.a=mgsin(theta)(k)(N)m.a=mgsin(theta)[kmgcos(theta)] Mass crosses out 3.1=(9.8)(sin29)k9.8cos29 Final answer k=0.193 Please inform me what am I doing wrong
