A block of mass = 50.0 kg is being dragged at a constant velocity across a floor by a strong person pulling it with a rope. The rope makes an angle of 300 with the horizontal. The tension in the rope is 50.0 Newtons. Assume a real floor, with friction. What is the coefficient of kinetic friction between the box and the floor?
A block of mass = 50.0 kg is being dragged aſ a constant velocity across a floor by a strong person pulling it with a rope. The rope makes an angle of 30° with the horizontal. The tension in the rope is 50.0 Newtons. What is the normal force exerted by the floor on the box?
5) A box of mass 25 kg is dragged across a level floor by a rope that makes an angle of 25o above the horizontal. The coefficient of friction between the box and the floor is 0.72. Find the force F that will ensure the box moves with constant speed.
Rachel is pushing a box across the floor while Jon, at the same time, is hoping to stop the box by pushing in the opposite direction. There is friction between the box and floor but you may ignore the effect of air resistance. Draw the force diagram for the box's motion and then choose the appropriate forces from the following list that should be included on the force diagram. Assume that the box is moving to the right during the...
A box is dragged 16 m across a level floor by a 75 N force acting at an angle of 35° to the surface. It is then dragged by the same force (same magnitude, same pulling angle) 8 m up a ramp inclined at an angle of 20% to the floor. Determine the total work done by the force. A box is dragged 16 m across a level floor by a 75 N force acting at an angle of 35°...
A 15.0 kg box is being pulled across a rough floor at a constant acceleration of 3.00 m/s^2 by means of a rope. The rope makes an angle of 34.0 degrees above the horizontal. The coefficient of kinetic friction between the floor and the box is u=0.250. Calculate the magnitude of the tension in the rope?
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?
4) Bubba pulls two boxes across the floor of his barn. One box has a mass (m1) of 20.4 kg and has a coefficient of kinetic friction of 0.321 with respect to the floor. The second box has a mass (m2) of 23.1 kg and a coefficient of kinetic friction of 0.177 with respect to the floor. The two boxes are connected with a rope. Bubba pulls on another rope connected to the second box. All of the ropes are...
a sled is pulled across a rough level floor at increasing speed. Which statement is true about the forces acting on the sled? a: the normal force is doing positive work b: the kinetic friction is doing negative work c: the weight of the cart is doing positive work d: the pulling force is doing negative work? Thank you so much!
