As indicated in the diagram below, a physicist sets up an experiment to determine the mass of a block. The block is put on top of a mass M stationary incline and gently released with a motor and pulley system, allowing the block to slide down the incline a distance s. As a result, on a well-lubricated platform, the inclination slides to the left a distance d. What is the mass m of the block if the mass of the motor and pulley system may be ignored? M d

Hoping for complete solutions since I’m having a hard time with this. Pls skip if unsure or not willing to answer the subitems (these are all connected for one item). Thanks in advanced! Consider the figure shown in the following figure. You are lowering two boxes, one on top of the other, down a ramp by pulling on a rope parallel to the surface of the ramp. Both blocks move with constant velocity. The coefficient of kinetic friction between the ramp and the lower box is 0.452 and the coefficient of static friction between the two boxes is 0.770. A. Draw the Free-Body diagram of both blocks. Set the x-axis parallel to the ramp. B. Write Newton’s 2nd law along the x and y directions for both blocks. C. What are the magnitude and direction of the frictional force on the upper box? D. What is the magnitude of the applied force? E. Determine the angle at which the top block will start to slide down the bottom block.

Let's now consider a slightly different case. The sled has a mass of 15 kg. The sled configuration is shown in the image below. YA 15 kg O O P When a child starts to pull the sled, it accelerates from rest to a velocity of 1.0 m/s. If it takes 10 seconds to get up to that speed (and we neglect friction), what is the magnitude of the force (in N) applied to the sled?

Check Your Understanding Suppose that Balto in Example 2.10 leaves the game to attend to more important matter, but Astro Clifford and Dug continue playing. Astro and Clifford’s pull on the toy does not change, but Dug rims around and bites on the toy in a different place. With how big a force and in what direction must Dug pull on the toy now to balance out the combined pulls from Clifford and Astro? Illustrate this situation by drawing a vector diagram indicating all forces involved.
