there is no friction between 50 kg and 10kg block's contact surface because there is no relative motion between them (since they both will stay on the wedge)
T is tension in the string
N1 is normal reaction b/w 5 and 50kg blocks, similarly for all other cases
and f1 is friction b/w 5 and 50 kg blocks and similarly for othe cases and g is acceleration due to gravity
Assume friction exists between each adjacent pair of boxes, and between the boxes and the floor....
4) Bubba pulls two boxes across the floor of his barn. One box has a mass (m1) of 20.4 kg and has a coefficient of kinetic friction of 0.321 with respect to the floor. The second box has a mass (m2) of 23.1 kg and a coefficient of kinetic friction of 0.177 with respect to the floor. The two boxes are connected with a rope. Bubba pulls on another rope connected to the second box. All of the ropes are...
If the coefficient of static friction between a box and the floor is 0.35 with what horizontal force does someone need to pull to get the box to move? The mass of the box is 28 kg.
A person pushes two boxes with a horizontal force of 100 N. The boxes are on a horizontal frictionless floor as shown in the fiqure below.

The UPS guy is delivering two rectangular boxes to the 4th floor. The boxes are stacked vertically in the elevator. The one on the bottom has a mass of 5.00 kg and the one on the top has a mass of 2.00 kg. The elevator, the UPS guy, and both boxes are accelerating upward at 2.50 m/s2. What is the magnitude of the normal force between the two boxes? For the physical representation (part 2a), draw and label an appropriate...
A set of eight boxes, 10.0 kg each, are stacked on top of a table, as shown in the figure below. (a) Draw a FBD of the top-most box and find the normal force exerted on it by the box below. (b) Draw a FBD of the 2nd box from the top, including all three (!) forces acting on it. Find the normal force acting on this box by the box below it. (c) Do you see a pattern now?...
Honorsphysic.sc# I ) Draw a FBD for each of the following : A) Mass on a ramp with a string pulling it up the ramp B) 2 unequal masses stacked in a moving elevator : Draw 2 FBD c) A person on the UFO ride @ a themepark that is stuck to a wall w/o touching their feet to the floor D) Two masses stacked (unequal masses) with the bottom mass being pulled by a tension force . The top...
two boxes are connected by a
cord running over a pulley. The coefficient of kinetic friction
between box A and the table is 0.31. Ignore the mass of the cord
and the pulley friction. In this case we can assume that the force
applied to one end of the cord will have the same magnitude at the
other end. Find a) acceleration, b) the Tension force FT
in the cord. Assume box A is twice the mass of box B...
A 30-kg box is at rest on a horizontal floor with friction coefficients μs = 0.65 (static) and μk = 0.55 (kinetic). You push on the box HORIZONTALLY (parallel to the floor) with varying applied force. For each applied force below, find the magnitude of the friction force exerted by the floor on the box (in Newtons), and state whether the friction is static or kinetic. (a) Applied force 100 N. (b) Applied force 150 N. (c) Applied force 190...
