When a skydiver is falling what happens to
a) her velocity
b) the air resistance?
a) Increases
b) increases
a) increases
b) decreases
a) increases
b) stays the same
a) stays the same
b) increases
Explain why the skydiver will eventually stop accelerating
The air resistance continues to increase as long as the velocity increases. When the air resistance reaches the same value as the weight there will be no resultant force, hence no acceleration (F=ma)
The air resistance continues to decrease as long as the velocity increases. When the air resistance is larger than the weight there will be no resultant force, hence no acceleration (F=ma)
The air resistance stays the same so the velocity increases. There will be no resultant force, hence no acceleration (F=ma)
The air resistance continues to increase as long as the velocity increases. When the air resistance reaches the same value as the weight there will be an increase in acceleration
