Answer:

C would make the most sense.

Explanation:

ok so basically the reason why i chose C is because i've always been told that whatever i type, send, or receive on my phone is stored into the phone's memory and can be brought back up with keystrokes. so yeah, i'd go with C but it's DEFINATELY not A or D.

A 1000 kg train car traveling at 12 m/s on a level track has 400 kg of sand dumped, vertically, into it. What is the final speed
crimeas [40]

Answer:

The final speed of the train car is 8.57 m/s.

Explanation:

Given that,

Mass of train car = 1000 kg

Mass of sand = 400 kg

Speed of train car = 12 m/s

We need to calculate the final speed of the train car after the sand is dumped

Using conservation of momentum

m_{1}u_{1}=(m_{1}+m_{2})v...(I)

Put the value in the equation (I)

1000\times12=(1000+400)v

v=\dfrac{1000\times12}{1400}

v=8.57\ m/s

Hence, The final speed of the train car is 8.57 m/s.
