A girl is pulling a 12.9 kg box with a force of 4.4 N at an angle of 300 with the horizontal. The box is moving at a constant speed.
What is the Normal force (in Newtons) on the box?

A8 kg box is being pulled across a horizontal surface. The pulling force has a magnitude of 55 N and acts at an angle of 30° above the horizontal. The coefficient of kinetic friction between the surface and box is 0.2. What is the normal force acting on the box?
You are pulling a 6.8 kg box with rope with a force of 5.5 N. The rope is 35° above thehorizontal. For a while you are pulling across ice that is very smooth. Later you reach a patch of snow which has a kinetic coefficient of friction of 0.2 and a static coefficient of friction of 0.35 with the box. A)Draw the free body diagrams for the box when it is on the ice and when it is on the...
A woman is pulling a 8 kg suitcase at constant speed by pulling a strap at an angle theta above the horizontal. She pulls on the strap with a force of magnitude 39 N. A horizontal retarding force of 23 N also acts on the suitcase. What normal force (in N) does the ground exert on the suitcase?
A woman is pulling a 9 kg suitcase at constant speed by pulling a strap at an angle theta above the horizontal. She pulls on the strap with a force of magnitude 32 N. A horizontal retarding force of 19 N also acts on the suitcase. What normal force (in N) does the ground exert on the suitcase

A 15.0-kg box is being towed by a child pulling on a rope at an angle of 20.0-deg above the horizontal with a force of 200.0-N. If the force of friction is 20.0-N, then what is the acceleration of the box across the floor?
A woman at an airport is towing, her 25.0-kg suitcase at constant speed by pulling on a strap at an angle theta above the horizontal. She pulls on the strap with a 40.0-N force, and the friction force on the suitcase is 20.0 N. Draw a free-body diagram of the suitcase. What angle does the strap make with the horizontal? What normal force does the ground exert on the suitcase?
3. A box having a mass equal to 10.0 kg is initially at rest on a horizontal, frictionless floor. A pulling force having a magnitude of 5.00 N is applied at an angle of 30.0° above the horizontal. The box is pulled a distance of 15.0 m. 7 ] = 5.00 N 30.0° (a) What is the work done by the pulling force? (b) What is the work done by gravity? (c) What is the work done by the normal...
3) A constant pulling force of 150 N applied at an angle of 21.7° above the horizontal, accelerates a crate across a rough horizontal surface. The has mass 35.2 kg, and the acceleration is 0.571 m/s. a) What is the normal force acting on the crate? b) What is the friction force acting on the crate? c) What is the coefficient of kinetic friction between surface?
explain why please
3.-In moving a 35.0-kg box from one side of a classroom to the other, a professor finds that a horizontal force of 300 N is necessary to set the box in motion, and a force of 240 N is necessary to keep it in motion at a constant speed. What are the coefficients of (a) static and (b) kinetic friction between the box and the floor? Starting the motion Moving at constant speed 300 N 35 kg...
