‼️ Parts E-H Only, do not need A-D The mass of block (m) is 30 Lb. The mass of block 4 () is 50 Lb, and the mass of block B (wa) is 75 Lb. You may neglect the masses of the pulleys, and you may assume that the blocks are initially at rest a) The equation(s) for position, velocity, acceleration, and displacement b) The displacement of the block at Bir A is pulled down a known distance of 3...

Constants Any event can be considered from different perspectives. In particular, the description of the motion of a given object would depend on the motion of the person describing the motion, the observer. Any such observer, equipped with a coordinate system anda stopwatch, forms a trame of reterence. Usually, we assume that a trame of reterence is attached to some object. For instance, "the trame of reterence of earth" means the observer is at rest relative to earth. In this...
A 220 B 70.6 C 319 D 12.7 E 44.6 F 56.7 Two blocks on a frictionless table are held at rest with a compressed spring between them. When the blocks are released, the spring pushes them apart and they move in opposite directions. The spring was compressed by 0.05 m. One of the blocks moves away at 0.28 m/s while the other moves away at 0.56 m/s. The heavier of the two blocks has a mass of 0.75 kg....
1.Whales have been determined to travel more or less in straight lines during migration. Occasionally they backtrack because of food. Find the displacement of Wanda the Humpback Whale over a week, traveling 88 north on Sunday, 14 north on Monday, 136 south on Tuesday, 26 north on Wednesday, 68 south on Thursday, 131 south on Friday, and 53 north on Saturday. All measurements are in kilometers. If the displacement direction is north leave the answer positive. If the displacement is...
Any assistance to get me started with (b), (C), (d) , and (e) would be appreciated. Thank you! A system consisting of two pulleys, a spring, and four masses connected by strings is shown in the diagram below. Masses 1 and 2 rest on the side of a frictionless ramp at an angle θ from horizontal. mass 3 is suspended by a pulley, and mass 4 is hanging from a spring of spring constant k displaced a distance d from...
