Simple Train Acceleration after elapsed time question

AI Thread Summary
A train accelerates to a speed of 4.6 m/s in 5.2 seconds, prompting a question about its speed after an additional 6.0 seconds with constant acceleration. To solve this, one must first calculate the acceleration using the change in speed and time. The formula v = v_0 + at is then applied to find the final speed. The discussion highlights the importance of determining acceleration before proceeding with further calculations. Acknowledgment of the initial oversight emphasizes the learning process in solving physics problems.

As a train accelerates away from a station, it reaches a speed of 4.6 m/s in 5.2 s.

If the train's acceleration remains constant, what is its speed after an additional 6.0s has elapsed?

I know I should be able to do this,but nothing I try works.If anyone could just point me the right way, I would really appreciate it. Thank You.

Well if you have the change in speed and change in time, then what is the acceleration? Then once you have that, you can plug that into:

v = v_0 + at
 
Thanks a lot, I really appreciate the help. I was going insane, but I realize I skipped the fact that I needed to find the acceleration first.

I won't make that mistake again. Once again thanks for the help!
 

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}...
