Ahot–air balloon is moving at a speed of 10 meters/second in the +x–direction. the balloonist throws a brass ball in the +x–direction at a velocity of +4 meters/second with respect to himself. if the ball lands after 30 seconds, about how far does it land horizontally from the point at which it was released?

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
