Forces in a Climb - Worksheet
1.  Assuming the angle of ascent is a constant, find the angle the plane must use to achieve this height at this distance --to the nearest degree. Make a diagram and explain how you arrived at your answer.
Note: Don't forget to change radians to degrees.

2. We are going to use this information to find vertical and horizontal net forces.

a. Find the thrust for a Boeing 737-600 airplane.
Thrust =____________

b. What is the take off weight of the plane? Change this weight to Newtons.
Weight in lbs. = ___________ Weight in Newtons =___________

c. Use the first equation on the Forces In A Climb page to find vertical net force. Use 700,000 N as the lift and 35,000 N as the drag.

Show the original equation and then show the substitutions with your answer. Label answer with correct units.

d. Use the second equation to find the horizontal net force; use lift and drag from part c above.

Show the original equation and then show the substitutions with your answer. Label answer with correct units.

3. Divide your net force from 2c and 2d by the weight of the airplane to get the vertical and horizontal acceleration in "g's" (ratioed to gravitational acceleration).

a. Vertical acceleration = _________________g's

b. Horizontal acceleration = _______________g's
