A 25 Okg Box Is At Rest On A Floor

A 25 kg box is pulled across a wooden floor with a rope.

A 25 okg box is at rest on a floor.

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. 9 4 learning objective 9 4 4 56. Match the appropriate quantity to each question.

The coefficient of friction between the box and floor is 0 21. A 3 0 kg and a 5 0 kg box rest side by side on a smooth level floor. A 25 kg box of books is dropped on the floor from a height of 1 1 m and comes to rest. What impulse did the floor exert on the box.

How fast does the box accelerate along the floor. A force of 75 n is exerted on the rope. A 12 n b 20 n c 24 n d 32 n e 0 n. A horizontal force of 32 n is applied to the 5 0 kg box pushing it against the 3 0 kg box and as a result both boxes slide along the floor.

Once moving what force in n is needed to keep it moving at a constant speed. A 25 kg box rests on a carpeted floor. A 3 0 kg and a 5 0 kg box rest side by side on a smooth level floor. The coefficients of friction are us 0 85 and uk 0 60.

A horizontal force of 32 n is applied to the 3 0 kg box pushing it against the 5 0 kg box and as a result both boxes slide along the floor. A 30 kg box is at rest on a horizontal floor with friction coefficients μs 0 65 static and μk 0 55 kinetic. What impulse did the floor exert on the box in kg. A cannot be answered without knowing how long it took the box to stop b 22 kg m s c 120 kg m s d 270 kg m s e 540 kg m s ans.

A 25 kg box of books is dropped on the floor from a height of 1 1 m and comes to rest. How hard do the two boxes push against each other. The rope makes an angle of 30o with the floor.
