A hand pushes a 2 kg block along a table from point A to point C as shown in the figure below. The table has been prepared so that the left half of the table (from A to B) is frictionless. The right half (from B to C) has a non-zero coefficient of friction equal to . The hand pushes the block the full distance from A to C using a constant force of 5 N. The block starts off...

Just asking help with Part I
A factory worker pushes a 30.0 kg crate a distance of 4.40 m along a level floor by pushing downward at an angle of 28.0° below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.260. The Crate is Pushed with Increasing Speed Now assume that, instead of the previous situation, the worker pushes harder (without changing the direction of his push), so that the crate moves with increasing speed....

3. A worker pushes constantly downward on a box of mass 43.0 kg with a force of 230 N at an angle of 26.0° from the horizontal. The box starts from rest and moves across a level floor for a distance of 3.66 m. The coefficient of kinetic friction is -0.384 230 N 43.66 m a) Show that the normal force on the box is 522 N. b) Find the force of friction on the box. c) What is the...

A hand pushes a 4 kg block along a table from point A to point C as shown in the figure below. The table has been prepared so that the left half of the table (from A to B) is frictionless. The right half (from B to C) has a non-zero coefficient of friction equal to u. The hand pushes the block the full distance from A to C using a constant force of 7 N. The block starts off...

A factory worker pushes a 30.0 kg crate a distance of 4.5 m along a level floor at constant velocity by pushing downward at an angle of 30° below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.25. Part A What magnitude of force must the worker apply to move the crate at constant velocity? Part B How much work is done on the crate by this force when the crate is pushed a distance of 4.5 m? Part C How...
