Explanation:
Given that,
Mass of a freight car,
Speed of a freight car,
Mass of a scrap metal,
(a) Let us assume that the final velocity of the loaded freight car is V. The momentum of the system will remain conserved as follows :
So, the final velocity of the loaded freight car is 0.182 m/s.
(b) Lost on kinetic energy = final kinetic energy - initial kinetic energy
Lost in kinetic energy is 8518.82. Negative sign shows loss.
Answer: velocity = -0.65 speed =0.65
Explanation:
Velocity =speed+direction speed =distance/time
