A block of 7.0 kg follows three paths. The darker squares respresent the initial locations, and the lighter squares represents the final locations. The initial height are all the same. The final heights are all the same. You will calculate the WORK done by the Gravitational force when the block follows each path. Draw the gravitational force vector. Draw displacement vector. Pay attention to the angle used in the work formula and the sign of work. DON't use scientific notation. Keep 2 decimal places. (1) What is the WORK (in Joules) done by the Gravitational force when the block follows path (1)

Lacie kicks a football from ground level at a velocity of 13.9 m/s and at an angle of 25.0° to the ground. how long will the ball be in the air before it lands? how far will the football travel before it lands?

Awave that is traveling fast can be said to have a high a. frequency b. speed c. wavelength d. amplitude e. period f. none of these

16. a brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800 n on him. the mass of the losing player plus equipment is 90.0 kg, and he is accelerating at 1.20m/s2 size 12{1 "." "20"" m/s" rsup { size 8{2} } } {} backward. (a) what is the force of friction between the losing player’s feet and the grass? (b) what force does the winning player exert on the ground to move forward if his mass plus equipment is 110 kg? (c) draw a sketch of the situation showing the system of interest used to solve each part. for this situation, draw a free-body diagram and write the net force equation.
