A Box Is Dragged Across A Floor

We know that the work done is equal to the product of force displacement and the angle between them.

A box is dragged across a floor. Which of the following would be closest to the coefficient of kinetic friction between the box and the floor if a 250 newton force on the rope is required to move the crate at a constant speed of 20 m s as shown in the diagram. A in terms of m μk θ and g obtain an expression for the magnitude of force required to move the box with constant speed. The box dragged at a distance of 10 m. A rope is tied to a box and used to pull the box 1 7 m along a horizontal floor.

A box with mass m is dragged across a level floor having a coefficient of kinetic friction μk by a rope that is pulled upward at an angle above the horizontal with a force of magnitude f. Tension in the rope t 100 n. A box is being dragged across the floor at a constant speed by a rope pulling horizontally on it. Part a identify all the forces acting on the box.

Mathematically it can be written as. Check all that apply. Kinetic friction force f k tension t weight w normal force n thrust f thrust. It is given that a box is dragged across a floor by a rope which makes an angle of 45 with the horizontal.

A box with mass m is dragged across a level floor having a coefficient of kinetic friction µk by a rope that is pulled upward with an angle θ above the horizontal with a force of magnitude f a in terms of m µk θ and g obtain an expression for the magnitude of force required to move the box with constant speed. A box with a mass of 50 kg is dragged across the floor by a rope which makes an angle of 30º with the horizontal. Use the following variables as necessary. A box is dragged a distance d across a floor by a force which makes an angle with the horizontal as in fig.

D first increases then decreases. G m mu k for μk and theta for θ. Friction is not negligible. Part b draw a free body diagram of the box.
