AI Thread Summary
The homework involves calculating the weight of a person with a mass of 120 lb (48 kg) using the formula w = mg, resulting in a weight of 470.4 N. The discussion confirms that this weight is correct. The next step is to determine the force required to push this weight up a 70-degree incline. Additionally, the problem includes calculating the magnitude and direction of the force needed for horizontal movement. The focus remains on applying physics principles to solve the incline and horizontal force components.

Homework Statement



Assume that force the force required to walk from home to school is on a 70 degree angle to the horizontal surface. This force is equal to your weight.
mass is 120lb or 48 kg
a) calculate weight.

The Attempt at a Solution



a)
w=mg
w=48kg*9.8N/kg
w=470.4N
IS THAT RIGHT?

470.4 N is the right weight. Now how much for does it take to push that weight up a 70 degree incline? I think that's the question.

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}...
