Grain is loaded onto a train initially coasting at the speed v0 m/s by dropping it vertically from a stationary silo at the rate αm kg/s. How fast is the train moving when it exits from under the silo (in m/s)?
Details
- The train is l=200 m long, and has an empty weight of m0=500 kg.
- v0=45 m/s
- αm=20 kg/s
