A balloon drifts 30 m toward the east in 8 s; then the wind suddenly changes and the balloon flies 50 m toward the west in the next 7 s. a. What distance did it travel during the first 10 s?
b. What distance did it travel during the next 5 s?
c. What total distance did it travel?

j. What was its average velocity during the first 10 s?
k. What was its average velocity during the next 5 s?
l. What was its average velocity for the entire trip?

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
