An American football player pushes horizontally (with a force of 91 N) on a heavy dummy bag (typically filled with sand and air) and moves it a distance 3.8 m along a horizontal ground at a constant velocity. After this, the player begins to weaken and applies their pushing force in an uneven manner, so that the force resembles a function that looks like Fx = (-x3 + 3x² +91) N for another distance 3.8 m. Determine the total work done by the player on the dummy bag.

A particle moves in the horizontal xy plane. A variable force acts on the particle with expression (in newtons) given by F =(4.10y+3.10)ȷ^, where y is in meters. Assume that even the particle's trajectory is a straight line from the position (in meters) r0=2.80ı^ +2.30ȷ^ to the position (in meters) rf=2.80ı^ +6.30ȷ^. Calculate the work done by this trajectory force and its de in joules, with three digits answers. ** only numbers in the answer **
A rectangular block has a length that is six times its width and a height that is three times its width. The block's surfaces are all identical except for size. When the block is placed on a horizontal tabletop so that the area in contact with the table is length ✕ width, it is found that a horizontal force of 11.6 N applied to the block is just sufficient to overcome the static friction force and cause the block to move. The block is then knocked over so that the area in contact with the table is length ✕ height. Now, what minimum horizontal force will cause the block to move?
A hockey puck with mass 0.166 kg is pushed across the ice with a constant force of 0.89 N. The coefficient of kinetic friction between the puck and the ice is 0.22. After a distance of 2.6 m, what is the puck's speed in m/s?
a student is skateboarding down a ramp that is 5.82 m long and inclined at 24.1% with respect to the horizontal. the initial speed of the skateboarder at the top of the ramp is 3.75 m/s. neglect friction and find the speed at the bottom of the ramp.
You are using a modified block and tackle pulley system to lift a concrete block. You need to lift the concrete block (mass=200kg) a distance of 5 meters upward. The system is designed to reduce the force loaded by a factor of 4. How much rope must you pull down on the other side of the pulley to lift the block the proper distance?
Problem 1: A 2.80kg block is placed on a rough (us=0.540) incline that makes an angle of 52.0° with respect to the horizontal. A pushing force horizontal to the ground is applied to the top of the block (This would make the force have an angle of 52.0° below the surface of the inclined plane, up the plane) to make the block stationary on the plane. What is the minimum pushing force needed to keep the block stationary on the plane? (10 points)
A hockey puck with mass 0.163 kg is pushed across the ice with a constant force of 0.37 N. The coefficient of kinetic friction between the puck and the ice is 0.13. After a distance of 1.3 m, what is the puck's speed in m/s?
Problem 5: Consider the vectors, D = (6.00î - 8.00j) m, B = (-8.00î + 3.00j) m, and A = (26.0î + 19.0j) m.
A worker pushes a 35.0-kg package on a horizontal roller-belt conveyor until it reaches a certain speed. The package then coasts on the horizontal conveyor, all the while slowing down, until it comes to a complete stop after moving 1.20 m. While the package is coasting on the conveyor, the opposing friction force averages 6.00 N. Use the WET to find the speed of the package after the worker pushes it and just as it begins to coast. 0.625 m/s 0.759 m/s 0.600 m/s 0.510 m/s 0.802 m/s 0.641 m/s
