This time, you pull the block horizontally, with a variable force, from x-0 to x-d. Again, calculate your work. F = A %3D (-1) • d = 22 meters %3D • A = 260 Newtons

1. Find the work done in the figure below. The magnitude of F= 50 N. The displacement is d= -3.0 m1 and 0 = 120°. d Ꮎ y Enter to 2 significant figures W = 75 F X Making sense: Do you predict positive, negative or zero work? Does your answer support the prediction?

Y A = 10 N 0 = 60° X 0 = 20° B = 14 N Calculate the following. Show all work (20 minutes) a) The magnitude and direction of A + B b) A• B с) Ах В

When the vector C⃗ is summed with the vector B⃗, the result is 9i ^ + 5j ^. Subtracting the vector B⃗ from the vector C⃗ results in 4i ^ −j ^. According to this: a) Show the vectors B⃗ and C⃗ in the unit vector notation. b) Determine the magnitude and direction (angle between C⃗ and the positive x-axis) of the vector C⃗. c) Find the scalar product (B⃗ .C⃗) of the vectors B⃗ and C⃗.

I included two pictures. Please show me how to approach the problem in the correct manner based on the feedback given. It is okay to completely change the answer if you need to. Please give a reasoning to why the claim is not reasonable and the work needed to back this up.

A process occurs in which a system's potential energy decreases while the system does work on the environment. Does the system's kinetic energy increase, decrease, or stay the same? Or is there not enough information to tell? Explain. Match the words in the left column to the appropriate blanks in the sentences on the right. positive negative zero unknown ‒‒‒‒‒‒‒‒‒‒ only the potential energy does the work the system does work on the environment Submit the mechanical energy does not change the change in potential energy may be greater as well as less than the work the system does on the environment the body cannot do more work than the change of its potential energy Request Answer The change in kinetic energy is because Reset Help

A block slides up an inclined plane. Friction is present between the block and the plane. Which of the following statements regarding the total energy of the block-Earth system is true? a. The total energy of the block-Earth system decreases because of the frictional interaction between the block and the plane. b. The total energy of the block-Earth system increases because of the increase in the vertical distance between the block and Earth's surface. c. The total energy of the block-Earth system remains the same because the net external force on the system is zero. d. The total energy of the block-Earth system decreases because of the decrease in the speed of the block.

Calculate the work done by friction as a 3.7 kg box is slid along a floor from point A to point B in the figure along paths 1, 2, and 3. Assume that the coefficient of kinetic friction between the box and the floor is 0.19. (Figure 1) Enter your answers numerically separated by commas.
