A 70 Kg Crate Is Pushed Across A Rough Floor

A crate is being pushed across a rough floor surface.

A 70 kg crate is pushed across a rough floor. A 25 kg crate is pushed across a rough horizontal floor to the right at a constant velocity with a force of 200 n directed 20 degrees below the horizontal which of the following statements at not true concerning the gravitational force on the crate. The coefficient of static friction between the crate and floor is 0 700 and the coefficient of kinetic friction is 0 600. If the crate of mass 15 kg moving at speed 6 m s comes to rest in 3 seconds what is the rate at which the frictional force on the crate takes energy away from the crate. A 20 0 kg crate is pushed across a rough floor for a distance of 90 0 cm.

Question 2 if i push a 9 kg crate across a rough floor at a constant speed of 5 5 m s for 10 seconds what net force is acting on the crate. A 10 kg box is placed initially at rest against the crate as shown at the moment the force is applied. A 20 0 kg crate is at rest on a floor as shown in. If no force is applied on the crate the crate will slow down and come to a stop.

If the crate of mass 50 kg moving at speed 8 m s comes to rest in 10 seconds what is the rate at which the frictional force on the crate takes energy away from the crate. 1 it has a magnitude of 250 n and points down.

F ma a vf vi t get more help from chegg. A horizontal force latex overset to p latex is applied to the crate. A uniform disc of mass and radius r is projected horizontally with velocity v c on a rough horizontal floor so that it starts off with a pure sliding motion at t 0. Draw free body diagrams of i the system ii the crate by itself.

If the coefficient of sliding friction is 0 25 what is the acceleration of the crate. A 50 kg crate is being pushed across a horizontal floor by a horizontal force of 575 n. A 50 kg crate is being pushed across a level frictionless floor by a force f 200 n. To move a large crate across a rough floor you push on it with a force at an angle of 15 degrees below the horizontal find the force necessary to start the crate moving given that the mass of the crate is 32 kg and the coefficient of static friction between the crate and the floor is 0 49.
