AI Thread Summary
To calculate the acceleration of an 8.5kg mass due to a proportional force, the relationship between force, mass, and acceleration must be understood. The correct formula is F = m * a, where force is the product of mass and acceleration. Given that a 1.7kg mass accelerates at 5.1m/s², the force can be calculated as 1.7 * 5.1. This force, when applied to the 8.5kg mass, allows for the calculation of its acceleration using the same formula. The final acceleration can be determined by rearranging the equation to solve for the new mass.

A force is applied to a 1.7kg mass and produces 5.1m/s^2 acceleration.
what acceleration would be produced by the same force applied to a 8.5kg mass? answer in units of m/s^2

ok... would i just use a proportion to get the answer to the problem? 1.7/5.1 = 8.5/x? Or do i need to find the force? If I am wrong i would appreciate some guidance in solving this!

Your proportion implies F = m / a, which is wrong. F = m * a.
 
oh... ok so it would be 1.7*5.1 =8.5*x

Correct. (1.7*5.1 is your force)
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

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}...
