A Box Is Dragged Across A Floor

Tension in the rope t 100 n.

A box is dragged across a floor.

A box is dragged across a floor by a rope which makes an angel 45 degree with the horizontal the tension in the rope is 100n while the box is dragged 10m the work done is. A box is being dragged across the floor at a constant speed by a rope pulling horizontally on it. We know that the work done is equal to the product of force displacement and the angle between them. A box is dragged a distance d across a floor by a force which makes an angle with the horizontal as in fig.

Part b draw a free body diagram of the box. Use the following variables as necessary. Kinetic friction force f k tension t weight w normal force n thrust f thrust. 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.

Check all that apply. D first increases then decreases. 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. 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.

If the magnitude of is held constant but the angle is increased the work done by a remains the same. Part a identify all the forces acting on the box. 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. 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.

G m mu k for μk and theta for θ. Friction is not negligible. A rope is tied to a box and used to pull the box 1 7 m along a horizontal floor. Mathematically it can be written as.
