What was the average power applied to the block if the whole displacement occurred...
Determine the work done by you in the following situations. A) Pulling horizontally with a force of 20 N on a 100 N sled. Sled moves 2 m at a constant velocity. (include units with answer) B) Pulling horizontally with a force of 40 N on a 100 N sled. Sled moves 2 m at a constant acceleration. (include units with answer) C) Pushing at 30° from horizontal with a force of 40 N on a 100 N sled. Sled...
A 20 kg box s initially at rest. Two forces drag. it across the floor, F_1 = 35 N i and F_2 = 35 N j, which cause a displacement of 3.5 m Imagine the x-y plane lies on the floor. (a) Draw the displacement vector and show (no need to calculate) the direction in which the package moves? (b) How much work is done by each force individually (F_1 and F_2)? (c) The coefficient of kinetic friction between the...

5 m with a A box of mass m = 1 k force that makes an angle of 35° above the horizontal with a magnitude of |F|-10 N, see the figure below. If the box's initial speed is vi = 1 m/s and the coefficient of kinetic friction between the box and the surface is -0.1, find the box's final speed vt. (For simplicity, you rnay use the magnitude of the acceleration due to gravity to be g...
1a. A horizontally directed force of 100 N is used to pull a box a distance of 5 m. How much work is done by the force? What is the change of kinetic energy of the box? 1b. At the lowest point in its swing, a pendulum bob with a mass of 0.1 kg has a velocity of 2 m/s. Ignoring the resistance of the air, how high will the bob swing above the lowest point before reversing direction? g=10...
Your friend is helping you slide a couch 4.7 m across the room. You pull with a force of 225 N at 35° above the horizontal from the front and she pushes from the other end with a force of 315N at 25 degrees from the horizontal. What is total work done?
3.) A 60.0 kg box is pulled by a 275 N force of tension provided by a rope pulled at an angle 30.0 degrees above the horizontal. The box moves 25.0 m horizontally as it is pulled by the rope.
