4. Bob and Sue are both pushing a box across the floor, but they are pushing in different directions. The force vector from Bob can be written as fge 40NI-2.0 N j and the force vector from Sue can be written as FSue-6,0 N t + 4.5 Nj. The speed of the box is in the direction of the net force on the box, and the force from friction is FFR 2.0 N. a) What is the resultant...

Two students are pushing identical crates across a frictionless floor. The crates are initially at rest. Bing applies a horizontal force of 19 N to his crate. Bob, who is shorter than Bing, pushes on his crate at an angle of 33° below the horizontal, also with a force of 19 N. Find the ratio of the masses of the two crates if Bing’s crate is moving at twice the speed of Bob’s crate after they have traveled a distance...

A man pushing a mop across a floor causes it to undergo two displacements. The first has a magnitude of 154 cm and makes an angle of 122° with the positive x axis. The resultant displacement has a magnitude of 147 cm and is directed at an angle of 38.0° to the positive x axis. Find the magnitude and direction of the second displacement.

A man pushing a mop across a floor causes it to undergo two displacements. The first has a magnitude of 146 cm and makes an angle of 114° with the positive x axis. The resultant displacement has a magnitude of 133 cm and is directed at an angle of 38.0° to the positive x axis. Find the magnitude and direction of the second displacement. I got 169 cm as the magnitude which was correct. However, I cannot find the direction.

A man pushing a mop across a floor causes it to undergo two displacements. The first has a magnitude of 152 cm and makes an angle of 128 with the positive x axis. The resultant displacement has a magnitude of 145 cm and is directed at an angle of 30.0° to the positive x axis. Find the magnitude and direction of the second displacement. magnitude direction cm o (counterclockwise from the positive x-axis)

A 5.3 kg box is pushed across a floor by pushing forward and down, with a force of 11.3 N at an angle 63.2 degrees from the horizontal floor. What is the normal force exerted by the floor onto the box?

Two workers are sliding a 300 kg crate across the floor. One worker pushes forward on the crate with a force of 380 N while the other worker pull in the same direction with a force of 350 N using a rope. Both forces are horizontal and the crate slides at a constant speed. What is the crate’s coefficient of kinetic friction on the floor?

Rachel is pushing a box across the floor while Jon, at the same time, is hoping to stop the box by pushing in the opposite direction. There is friction between the box and floor but you may ignore the effect of air resistance. Draw the force diagram for the box's motion and then choose the appropriate forces from the following list that should be included on the force diagram. Assume that the box is moving to the right during the...

Two playful cats are pushing on either sides of a 3.0 kg box that can move over a very slippery floor. The black cat pushes with a 9.0 N force, acting due east, while the yellow cat uses a 8.7 N force, pushing 49° north of west. What is the magnitude of the box's acceleration? Assume that the cats are pushing perfectly horizontally to the floor (no vertical forces).

While moving in, a new homeowner is pushing a box across the floor at a constant velocity. The coefficient of kinetic friction between the box and the floor is 0.423. The pushing force is directed downward at an angle θ below the horizontal. When θ is greater than a certain value, it is not possible to move the box, no matter how large the pushing force is. Find that value of θ.
