How Is the Distance of 262m Calculated for a Particle Accelerating from Rest?

AI Thread Summary
The discussion revolves around calculating the distance a particle travels while accelerating from rest over a 20-second period. The provided answer is 262 meters, but the method of calculation is unclear to the original poster. It is noted that the particle accelerates at 2 m/s² for the first 10 seconds, remains at constant velocity for the next 5 seconds, and then decelerates at -3 m/s² for the final 5 seconds. Participants are encouraged to share relevant kinematic equations and demonstrate their problem-solving attempts. The thread emphasizes the importance of breaking down the motion into distinct time intervals to accurately compute the total distance.

Profcocoon, welcome to PF!

From your graph, the acceleration appears to be 2 m/s^2 for the first 10 seconds; then there is no acceleration for the next 5 seconds; and then it accelerates at -3 m/s^2 in the final 5 seconds.

Please list what you think are the relevant equations, and show some attempt at a solution using the relevant kinematic equations over the different time periods. You must show some attempt before we can be of further assistance.
 
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}...
