Differential equation of motion

AI Thread Summary
The discussion focuses on finding the maximal ground reaction force when the initial speed is zero, expressed as a multiple of body weight. The relevant equation of motion is given as Y1(t) = A sin(ωt) + B cos(ωt) + g/ω^2, where ω is the angular frequency defined as √(k/m). Participants are seeking clarification on the initial conditions needed to solve for constants A and B, given that y=0 and Vo=0. The conversation emphasizes the need for additional initial conditions to progress with the solution. Understanding these parameters is crucial for accurately determining the ground reaction force in this scenario.

Homework Statement



Find the maximal ground reaction force for the limiting case where the speed at initial contact is equal 0 (Vo=0) expressing it as a mulitple of the body weight (mg)
ω = √k/m

Homework Equations



Y1(t) = A sinωt + B cos ωt + g/ω^2

The Attempt at a Solution



I know A and B are constants based on the initial conditions but as y=0 and Vo= 0 and there is no x componant - what other initial conditions can I use?

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
