AI Thread Summary
To find the change in momentum of a 4.5 kg object projected at a 53° angle and hitting the ground after 3.6 seconds, the initial and final velocities must be calculated using kinematic equations. The momentum change can be determined by the formula P = mv, where m is the mass and v is the change in velocity. Since air resistance is ignored, the calculations focus solely on the vertical and horizontal components of motion. The discussion emphasizes the need to derive the final speed to complete the momentum calculation. Understanding these principles is crucial for solving the problem accurately.

Homework Statement



An object of mass 4.5 kg is projected into the air at a 53° angle. It hits the ground 3.6 s later. What is its change in momentum while it is in the air? Ignore air resistance.

Homework Equations



P = mv V=Ft/m

The Attempt at a Solution



I'm not sure how to find the velocity for this question, otherwise I know how to find the answer.

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}...
