10. A railroad hopper car is filled with sand and rolling with an initial speed of V; on straight, horizontal tracks. You can ignore frictional forces on the railroad car. The total mass of the car plus sand is Mtotal. The hopper door is not fully closed, so that sand leaks out of the bottom. After some time t, mass M= '/¼M1otal has leaked out. What is the speed of the railroad car at time t? MauiAL sand + (ar Sand le aking out

A railroad hopper car is filled with sand and rolling with an initial speed of Vi on straight, horizontal tracks

 

10. A railroad hopper car is filled with sand and rolling with an initial speed of V; on straight, horizontal tracks. You can ignore frictional forces on the railroad car. The total mass of the car plus sand is Motal. The hopper door is not fully closed, so that sand leaks out of the bottom. After some time t, mass M= '/4M1otal has leaked out. What is the speed of the railroad car at time t? MauiAL sand + (ar Sand le ating out
