A train is traveling up a 3.9 degrees incline at a speed of 3.15m per s when the last car breaks free and begins to coast without friction. How long does it take for the last car to come to rest?
the answer in the back of the book is 4.7 sec and i just can't figure it out I don't get how the book got 4.7 seconds. I got .02 seconds because v=vo+at or velocity= initial velocity + acceleration *time. Thus, -.2/-9.81= .02 seconds. Vinital=3.15m/s A=gsin(3.9) V=0 0=3.15m/s+9.81m/s^2*sin(3.9)t So, -3.15m/s/(.667m/s^2)=t t=-4.7

How far will a falling object move in 9 seconds?
We can find the velocity after 8 seconds using the equation v = v0 + at, sov = 0 + (9.8)(8), v = 78.4. We can then use the equation v2 = v02 + 2ax to find how far it will fall:78.42 = 02 + 2(9.8)xx = 78.42/(2*9.8) = 313.6The object will fall about 313.6 meters.(Your final answer may differ a little due to rounding differences.)
