Question:

4. [4 Points] The object shown has mass m is placed at the bottom of an inclined plane that has a length of d and vertical he

4. [4 Points] The object shown has mass m is placed at the bottom of an inclined plane that has a length of d and vertical height of h. The block is being pulled all the way to the top at a constant velocity v by an applied force F. Part 1: What is the initial potential energy of the block? a. Zero b. mgh c. -mgh d. mgd e. -mgd f. The answer depends on your personal choice of where to set Ug = 0. Part 2: What is the final potential energy of the block? a. Zero b. mgh c. -mgh d. mgd e. -mgd f. The answer depends on your personal choice of where to set Ug = 0. Part 3: What is the change in the potential energy of the block (U, – U.)? a. Zero b. mgh c. -mgh d. mgd e-mgd f. The answer depends on your personal choice of where to set Ug = 0. Part 4: What is the change in the kinetic energy of the block? a. Zero b. mgh - Fd c. -mgh+Fd d. mgh + Fd e. mgh f. -mgh g. Fd

To find the conversion between two of these units, divide the number of kilometers in one by the number of kilometers in another. For example, 1 mile = 1.61 kilometers and 1 meter = 10-3 kilometers. So 1 meter/ 1 mile = 10-3 kilometers / 1.61 kilometers = 6.21 x 10-4. Therefore, 1 meter = 6.21 x 10-...
