Explorers in the jungle find an ancient monument in the shape of a large isosceles triangle as shown. The monument is made from tens of thou- sands of small stone blocks of density = 800 kg/m3 . The monument is 15.7 m high and 64.8 m wide at its base and is everywhere 3.60 m thick from front to back. Before the monument was built many years ago, all the stone blocks lay on the ground. (a) Choosing a coordinate system with x = 0 at the center of the pyramid, y = 0 at the base of the pyramid, and z = 0 at the face of the pyramid shown in the diagram, determine the coordinates of the center of mass of the pyramid in the x, y, and z directions. (b) How much work did laborers do on the blocks to put them in position while building the entire monument? Note: The gravitational potential energy of an object–Earth system is given by Ug = MgyCM, where M is the total mass of the object and yCM is the elevation of its center of mass above the chosen reference level.
A Pyramid with nonuniform density p = (p0/(y3(y+1))) (p0 is the average density) with mass M, square base a2, and height h, find the y center of mass of the Pyramid in term of h. (??????? ?????? = 1/3 * base^2 * height)
This question is all that is given. please give the answer in a ratio to the height. ie 3/4h

- A metal plate has a horizontal width of 3 m and a vertical height of 2 m. The density of the plate is uniform, meaning that the mass is evenly distributed.

Infront of him was a pickup truck that was carrying plastic chairs and several other items. The chairs were stacked high one over the other and a cable tie was used to secure the chairs to the truck. Suddenly the cable tie snapped open and several chairs fell onto the road. Alarmed, Husin slammed on his brake but his car spinned around and hit the road divider instead. As his car came to a stop, another motorcycle hit his car from behind. The rider, Ben was flung to the ground and he suffered serious injury from the impact. Husin too sustained cuts and a concussion in the incident. Discuss whether Husin would be successful if he were to sue the truck driver for his injury.arrow_forwardWhich one of the following is true concerning momentum?
