Web3.7 Two masses 26 kg and 24 kg are attached to the ends of a string which passes over a frictionless pulley. 26 kg is lying over a smooth horizontal table. 24 N mass is moving vertically downward. Find the tension in the string and the acceleration in the bodies. (125 N, 4.8 ms – 2) Solution: : WebMr. Burton. 7 years ago. In the video, the masses are given to us: The 9 kg mass is falling vertically, while the 4 kg mass is on the incline. The forces of gravity, or Weight, is directly proportional to mass, and both be positioned vertically. 3 comments.

WebSketch the situation, using arrows to represent all forces. Determine the system of interest. The result is a free-body diagram that is essential to solving the problem. Apply Newton’s second law to solve the problem. If necessary, apply appropriate kinematic equations from the chapter on motion along a straight line. WebNov 8, 2024 · You're assuming you're calculating the kinetic energy right before the mass hits the ground.. If the mass strikes the ground, it will naturally lose nearly all of its kinetic energy to liberate heat, make sound, create deformations, and possibly displace the plane. rcn portfolio online
