When Will Particle B Pass Particle A in 2 Particles, 1 Direction?

AI Thread Summary
To determine when Particle B will pass Particle A, the distances traveled by both particles must be equalized using the kinematic equation d = V_it + 1/2 at^2. Particle A's distance equation is 6.4t + 0.85t^2, while Particle B's is 2.2t + 2.5t^2. By setting these equations equal and solving for time, the point at which Particle B overtakes Particle A can be calculated. The discussion emphasizes the importance of correctly applying the kinematic formula to find the solution. The final answer will provide the time in seconds when Particle B passes Particle A.

Two particles are at the same point at the same time, moving in the same direction. Particle A has an inital velocity of 6.4 m/s amd am acceleration of 1.7m/s^2. Particle B has an initial velocity of 2.2 m/s and an acceleration of 5 m/s^2. At what time will B pass A? Answer in units of s.

Use the following kinematics formula and equal the distances they travel. Then, solve for time.

d = V_it+ \frac{1}{2}at^2
 
so its 6.4t+1/2*1.7t^2=2.3t+1/2*5t^2 ?
 
precisely :!)
 
got it thanks

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}...

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...
