Hang a mass from a spring. We are interested in the moment where you pull the mass down (before you release it) to the highest point that the mass moves to. We also care about when the mass is moving its fastest. In this case, the best place to put the zero reference is where the mass is hanging before you pull on it. 1)Draw an LOL Diagram 2)What is the energy model equation? 3)Will energy be conserved? (i.e., does ΔEsys =0?)

Given the sketch shown below, the diameter of the plunger Dp = 8 cm. The Ram diameter is Dr = 48 cm. The efficiency is 100%, the stroke of the plunger is 18 cm. The ram has to raise a load F2 = 2kN. Find: A) the force f1 exerted on the plunger. B) the number of strokes needed to raise the load given above by a distance of 10 cm. C) the volume of oil pumped if the load moves by 20 cm ( using plunger force in a ) D) what will be the new diameter of the ram piston if the new load force is 16 times the force exerted in the plunger the diameter of the plunger is kept to 8 cm.

I need an answer with a free body-diagram. Show all work as quickly as possible. Q: A wooden plank of negligible mass and length L = 2.8 m is used to keep in balance, horizontally, a small cube of mass 20.0 kg when applying a force F of 80.0 N at one end of the board. The distance, in meters, between the support point of the board and the position where find the cube is: a) 0.56 b) 0.80 c) 1.00 d) 1.12 e) 1.40

Physics 121 Spring 2021 - Document #11: Homework #04 & Reading Assignment page 4 of 8 Problem 1: Gnome Ride - This from a Previous Exam I. A Gnome of given mass M goes on the Gnome Ride as follows: He stands on a horizontal platform that is connected to a large piston so that the platform is driven vertically with a position as a function of time according to the following equation: y(t) = C cos(wt) Here w is a constant given angular frequency, C is a given constant (with appropriate physical units) and y represents the vertical position, positive upward as indicated. Part (a) - What is the velocity of the Gnome at time t = 0? Explain your work. Present your answer in terms of the given parameters Part (b) – What is the net force on the Gnome at time t = 0? Explain your work. Present your answer in terms of the given parameters Part (c) – What is the Normal Force on the Gnome at time t = 0? Explain your work. Present your answer in terms of the given parameters Some Possibly Useful…
