Scenario Number Final Velocity of Cart X Final Velocity of Cart Y 1 0 vy1
2 vx2 vy2
3 -vx3 vy3

Cart X then collides with cart Y of mass Mo, which was initially at rest. After the collision, cart Y has a positive velocity. Immediately after the collision, cart X and cart Y could have one of three final velocities that are indicated in the table. In all scenarios, the total momentum of the two-cart system is the same before and after the collision. Assume that the collision in each scenario is elastic. How does the magnitude of the change in the momentum Îp of Object Y compare for each scenario?

Agroup of students is studying convection currents. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other in an area with warm air. after 10 minutes, the balloons are released from a height of 1 meter. which of the following do the students most likely observe? question 2 options: the balloons rise at the same rate. both balloons are the same size. the ballons both rise. the cold ballon is larger than the warm balloon. the cold balloon expands and rises. the warm balloon shrinks and sinks. the warm balloon expands and rises. the cold balloon shrinks and sinks.
