A crate sits on wooden horizontal surface (a wooden floor). The figure shows a top view of this looking down onto the crate (gravity would be acting into the page). Man one and man two apply forces F1 and F2, at angles of θ1 and θ2 respectively, with the goal of moving the crate in the x-direction. A resultant force of Fr = 31 lbs in the x-direction is required to accomplish this. All of the forces are in the...

1. A 200 kg crate is pushed across a floor by a force F = 250 newtons at an angle 0 = 53 below horizontal. The floor exerts a 50 newton frictional force on the crate opposing the motion. a. Draw a labeled free body diagram showing the forces acting on the trunk. (+2) b. Below, write Newtons's 2nd Law (F = må) in the horizontal (x) and vertical (v) direction, using the names of the forces from your free...
A block with a mass of m=37 kg rests on a frictionless surface and is subject to two forces acting on it
Problem 5: A block with a mass of m=37 kg rests on a frictionless surface and is subject to two forces acting on it. The first force is directed in the negative x-direction with a magnitude of F1=8.5 N. The second has a magnitude of F2 = 19.25 N and acts on the body at an angle θ = 17° measured from horizontal, as shown.Part (a) Please use the interactive area below to draw the Free Body Diagram for this...

General Physics
Problem 4: At a local swimming pool, the diving board is elevated h = 9.5 m above the pool's surface and overhangs the pool edge by L = 2 m. A diver runs horizontally along the diving board with a speed of vo = 4.8 m/s and then falls into the pool. Neglect air resistance. Use a coordinate system with the horizontal x-axis pointing in the direction of the diver's initial motion, and the vertical y-axis pointing up....

A Review | Constants Part A A 57.0 kg crate of tools rests on a horizontal floor. You exert a gradually increasing horizontal push on it, and the crate just begins to move when your force exceeds 313 N. Then you must reduce your push to 208 N, to keep it moving at a steady 25.0 cm/s. What are the coefficient of static and kinetic friction between the crate and the floor? Enter your answers numerically separated by a comma....

An object with weight W is dragged along a horizontal plane by a force acting along a rope attached to the object. If the rape makes an angle with the plane, then the magnitude of the force is F= u sin() + cos(8) where u is a constant called the coefficient of friction.
