Force Question Using weight and acceleration

AI Thread Summary
To calculate the force exerted by a 50 kg person in an elevator accelerating upward at 1 meter per second squared, Newton's second law (F = ma) is applied. The person exerts a force equal to her weight plus the additional force from the elevator's acceleration. The weight of the person is 50 kg multiplied by the acceleration due to gravity (approximately 9.81 m/s²), which equals 490.5 N. Adding the force from the upward acceleration (50 kg * 1 m/s² = 50 N) results in a total force of 540.5 N. Therefore, the person exerts a force of 540.5 N while the elevator accelerates upward.

Question: A 50 kg person stands on an elevator. How much force does she exert if the elevator accelerates upward at 1 meter per second squared?



I know she exerts 50 kg of force while the elevator is stationary, but I don't know the formula for when the elevator moves.

Draw a free body diagram on the person and write out Newton's second law. Remember that the force the ground exerts on the person is equal to the force the person exerts on the ground.
 

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}...
