Can anyone help me on this one? Thanks!
a. Find the speed of the skydiver when the parachute opens.
b. Find the distance fallen before the parachute opens.
c. What is the limiting velocity vL after the parachute opens?
d. Determine how long the sky diver is in the air after the parachute opens.
e. Plot the graph of velocity versus time from the beginning of the fall until the sky diver reaches the ground.
Answer:
g = 6
Step-by-step explanation:
3.8g + 8 = 1.8g + 20
Subtract 1.8g from both sides;
2g + 8 = 20
Subtract 8 from both sides;
2g = 12
Divide both sides by 2;
g = 6
You can check if the value of g is correct by plugging in the value of g to the equation. If your check does not it doesn't mean your answer is not correct because sometimes it can be a no solution equation which means that there is no solution to the equation.
Check:
3.8(6) + 8 = 1.8(6) + 20
22.8 + 8 = 10.8 + 20
30.8 = 30.8
It means its correct
