WebFriction must be treated with care in a situation like this. If the hanging mass is large enough to overcome friction and accelerate the mass upward on the incline, then the friction force will oppose it and act downward. If the mass on the incline is large enough, it will overcome friction and move downward, pulling the hanging mass upward. WebIf the coefficient of friction force between block and inclined plane is 0.4, what is the acceleration of the block. Known : Object’s mass (m) = 5 kg Acceleration due to gravity (g) = 10 m/s2 weight of block (w) = m g = (5)(10) = 50 Newton Force F = 71 Newton Sin 37o= 0.6 Cos 37o= 0.8 Coefficient of friction = 0.4

WebAnswer: 10250 lbs. Hint and answer for Problem # 8. In the equation T2 = T1eμθ, we have T2 = 50 kg, T1 = 40 kg, and θ = π. We can then solve for μ, and this is the minimum … WebThe problem quickly becomes a one-dimensional problem along the direction of →Fapp, since friction is in the direction opposite to →Fapp. Our strategy is to find the magnitude and direction of the net applied force →Fapp and then apply Newton’s second law to solve for the drag force →FD.
