1. The problem statement, all variables and given/known data A series of small packages, each with a mass of 4 kg, are discharged from a conveyor belt as shown. Assume that the coefficient of static friction between each package and the conveyor belt is 0.4. Determine the force exerted by the belt on a package just after it has passed Point A I attached the picture below 2. Relevant equations F = ma 3. The attempt at a solution So I began by drawing a FBD: -W: Weight pointed downwards -N: Normal pointed upwards -f: Friction pointed left -B: Force from the belt pointed right. From what I understand, we are trying to solve for B. Also, it is about to enter a circular region, which makes me think that the net acceleration is -mv^2/r in the y direction and dv/dt in the x direction. So, I began by solving the forces in the y direction: -mv^2/r = -W + N -(4)(1^2)/(0.250) = -(4)(9.81) + N --> N = 23.24 N From there, I setup the equation in the x direction: dv/dt = B - (u)N dv/dt = B - (0.4)(23.24) Now the thing is, I assumed that the speed is consistent which would imply B = (0.4)(23.24) = 9.296 N. However, this answer was wrong, so I am not sure how to approach it from here.
