Projectile Motion of Apple Core from a Tree

AI Thread Summary
The discussion focuses on calculating the projectile motion of an apple core thrown from a height of 4.0 meters with an initial velocity of 5.0 m/s at an angle of 35 degrees. Participants are asked to determine the time it takes for the apple core to hit the ground, the horizontal distance it travels from the base of the tree, and its impact velocity. The calculations involve breaking down the initial velocity into horizontal and vertical components and applying kinematic equations. Users are encouraged to show their attempts at solving these problems to receive assistance. The thread aims to clarify the principles of projectile motion in a practical scenario.

A child sitting in a tree throws his apple core from where he is perched (4.0 m high) with a velocity of 5.0 m/s [35o above the horizontal], and it hits the ground right next to his friend.
a) How long is it before the apple core hits the ground?
b) How far from the base of the tree will the apple core land?
c) What is the velocity of the apple core on impact?

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}...
