AI Thread Summary
The discussion focuses on understanding the acceleration graph of a girl jumping on a trampoline. Key points include analyzing her motion at different stages: at the peak of her jump, she experiences downward acceleration; while falling, her acceleration is influenced by gravity; and upon hitting the trampoline, she experiences a sudden change in acceleration. The acceleration will vary throughout her jump, being negative during the ascent and descent, and positive when compressing the trampoline. A clear understanding of these phases is crucial for accurately depicting the acceleration graph over time.

Homework Statement



A girl jumps up and down several times on a trampoline( sheet stretched horizontally by springs at the sides). What will the graph of her acceleration as a function of time look like?


Homework Equations



i don't think one is needed

I have no idea what to do!

First try to describe the motion in words. When she is at the top of her jump, will she be accelerating up or down? How about when she is halfway through falling? And what about when the hits the trampoline? When she is halfway back up to the top of her jump, will she be speeding up or slowing down?
 

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}...
