Force constant of rear suspension of car

AI Thread Summary
To calculate the force constant of a car's rear suspension when a 110 kg box causes a 13 cm decrease in bumper height, Hooke's Law (F = kx) is applicable. The force (F) exerted by the box can be calculated using the weight formula, F = mg, where m is the mass and g is the acceleration due to gravity. The displacement (x) is the change in height, which is 0.13 meters. By rearranging Hooke's Law to solve for the spring constant (k), the formula becomes k = F/x. This approach provides a clear method for determining the force constant of the suspension system.

Can anyone help with the formula set ups for this ?

A 110 kg box is loaded into the trunk of a car. If the height of the car's bumper decreases by 13 cm, what is the force constant of the rear suspension ?

Sounds like a Hooke's law problem, F = kx, k is the spring (force?) constant, and x is the displacement from the equilibrium position, how much the spring is compressed or stretched. Does this help?
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
