I don't understand what I'm looking for: 1. A 2.5-kg mass is traveling to the left at 2.0 ms-1. It then experiences an impulse represented in the F vs. t graph shown here. What is the total impulse given to the ball?
2. What is the change in momentum of the ball?
3. What is the final velocity of the ball?

Isobars are lines of constant or equal pressure on a weather map. they can be used to find areas of low or high pressure over a broad area, and they can tell us how intense the system may be. on weather maps, you may have noticed areas that have a large l or h over a region with lines circling around them. the l stands for low pressure and h stands for high pressure. the lines circling them are isobars. check out the pressure system and isobars over georgia and florida. what is the present weather in this area ? a) clear and sunny b) cold and cloudy c) changing weather d) lots of precipitation
