Four 5.8-kg packages are placed as shown on a conveyor belt which is disengaged from its drive motor. Package 1 is just to the right of the horizontal portion of the belt. If the system is released from rest, determine the velocities of packages 1and 2 as they fall off the belt at point A. Assume that the mass of the belt and the rollers is small compared with the mass of the packages and that there is no slipping...
A horizontal force, F1=55 N, and a force, F2 = 17.6 N acting at an angle of θ with respect to the x-axis, as shown, are applied to a block of mass m=2.4 kg.
A horizontal force, F1=55 N, and a force, F2 = 17.6 N acting at an angle of θ with respect to the x-axis, as shown, are applied to a block of mass m=2.4 kg. The coefficient of kinetic friction between the block and the surface is μk = 0.2. The block is moving to the right.Part (a) Solve numerically for the magnitude of the normal force, FN in newtons, that acts on the block if θ = 30°. Part (b) Solve...

m1 A block with mass my = 9.4 kg is on an incline with an angle 6 = 33 with respect to the horizontal. For the first question there is no friction between the incline and the block. 1) When there is no friction, what is the magnitude of the acceleration of the block? m/s2 Submit 2) Now with friction, the acceleration is measured to be only a = 3.63 m/s2. What is the coefficient of kinetic friction between the...

A block with mass 12.0 kg is on a ramp that is inclined at an angle of 50.0 degrees above the horizontal. The block is accelerating up the ramp at 3.0 m/s2 as you pull on it with a string parallel to the surface of the ramp with a constant force of 140 N.\ A) Draw a free body diagram for the block moving up the ramp and choose a convenient xy-coordinate system to apply Newton's laws of motion.
