The 379-kg (MA) and 265-kg (mg) mine cars are rolling in opposite directions along the horizontal track with the respective speeds of 0.37 m/s (VA) and 0.46 m/s (vg). Upon impact the cars become coupled together. Just prior to impact, a 141-kg boulder leaves the delivery chute with a velocity of v= 1.24 m/s in the direction shown and lands in the 379-kg car. Calculate the velocity v₁ of the system after the boulder has come to rest relative to the car. Also, calculate the final velocity v₂ if the cars were coupled before the boulder dropped. The velocities are positive if to the right, negative if to the left. Assume = 35°. 8 Answers: V1 = V2 MA i i 0 VB O m/s m/s
