Calculating Spring Force Constant from a Dropped Ball

AI Thread Summary
To calculate the spring force constant k, the conservation of energy principle is applied, equating the gravitational potential energy of the dropped ball to the elastic potential energy stored in the spring at maximum compression. For the 86.3g ball dropped from 52.3cm, the energy conversion leads to the formula k = (m*g*h) / (0.5*x^2), where m is the mass, g is the acceleration due to gravity, h is the height, and x is the maximum compression of the spring. A similar scenario with a 135g ball dropped from 62cm can be analyzed using the same method, adjusting the values accordingly. The calculated spring constant k will be expressed in units of N/m. This approach effectively demonstrates the relationship between gravitational force and spring compression.

A 86.3g ball is dropped from a height of 52.3cm above a spring of negligible mass. The ball compresses the spring to a maximum displacement of 4.9296 cm. The acceleration of gravity is 9.8m/s^2. Calculate the spring force constant k. answer in units of N/m.

Conservation of energy ofcourse. :)
Take the reference level as the level at which the spring is compressed to the maximum displacement. Do you think you can go from there?
 
i have a similar question, except with different values.

135 g for mass of ball

62 cm above spring

9.8 is same for gravity
 
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
