14) Three blocks are connected by ideal, meaning massless and inelastic, ropes which pass over ideal, meaning massless and frictionless, pulleys. When released from rest, or perhaps given a slight nudge, the system begins to accelerate with the red block descending towards the floor. There is a friction between either block and its respective surface, μ₁. Find the acceleration and each tension force in the ropes.

The 17-Mg truck hauls the 33-Mg trailer. If the unit starts from rest on a level road with a tractive force of 25 kN between the driving wheels of the truck and the road, compute the tension T in the horizontal drawbar and the acceleration a of the rig. 33 Mg 17 Mg O O O O O Answers: T= i a= i KN m/s² O

A person on a sled starts descending from the highest point of a snowy slope with a 30º inclination and 150 m in length. The combined mass of the person and the sled is 90 kg. At the end of the slope, they continue moving on a horizontal track until they stop. The coefficient of friction between the sled and the snow is \( \mu = 0.18 \) in both cases. 1. Draw the forces acting on the sled in each section.  2. Calculate the mechanical energy dissipated due to friction on the inclined section.  3. With what speed does it reach the end of the slope?  4. What distance does the sled travel on the horizontal plane before stopping?

Current Attempt in Progress A flatbed truck is carrying a crate up a hill of angle of inclination 8 = 8.90°, as the figure illustrates.

A(n) 19_kg mass is on an incline, with a = 4.5_m and b = 2.3_m. The coefficient of kinetic friction between the mass and the surface of the incline is µg = 0.36. If the mass is initially near the top of the incline and sliding down, then what is the mass's acceleration down the incline? m b
