Using tUsing the information and figure below, answer Questions 1-12 about a small, single-stage experimental test.

	Standard figure for Earth Gravity (g0)		32.174 ft/s2
	Launch Weight (w0)		16.0 lbf
	Useful Propellant Weight (wp)		1.5 lbf
	Effective Specific Impulse (Is)		136 s
	Launch Angle () Relative to Horizon		65
	Burn Time with Constant Thrust (tp)		2.2 s

1. Calculate the thrust (F) produced by this rocket during its powered flight stage. (3 Points)

F = (w0 + wp)*g0/Is = (16. 0 lbf + 1. 5 lbf)*32. 174 ft/s2/136 s = 24. 70 lbf

1. Calculate the initial accelerations along the (a) y-vertical (a0)y and (b) x-horizontal (a₀)_xthe directions during powered flight. (3 Points per Part)

a0x = F*cos() = 24. 70 lbf*cos(65) = 8. 143 ft/s2; a0y = F*sin() = 24. 70 lbf*sin(65) = 21. 91 ft/s2

1. Calculate the final acceleration (a₀) at thrust termination. (3 Points)

3. a0 = F/By = 24. 70 lbf/By = 24. 70 lbf/2. 2 bf/s2 = 11. 23 ft/s2

1. Calculate the exhaust gas velocity (c) for this rocket. (3 Points)

1. Calculate the (a) vertical and (b) horizontal components of the velocity (u_p) at thrust termination. (3 Points per Part)
2. Determine the trajectory angle with the horizontal at thrust termination. (4 Points)
3. What is the final acceleration (a_f) based on the final mass of the rocket? (4 Points)
4. Determine the (a) vertical (y_p) and (b) horizontal (x_p) components of the distance traveled during Powered flight for this rocket. Note: This calculation in the Example is incorrect. (3 Points per Part)
5. Calculate (a) theUnpoweredportion (from Power off to Zenith) of the height gained or (y_z y_p) and (b) the total, orZenithheight (y_z) for this test flight. (2 Points per Part)
6. Calculate (a) the time (t_z) it takes for the rocket to descend from Zenith back to the ground and (b) the final vertical (impact) velocity (u_f)_yfor the rocket. (2 Points per Part)
7. What is (a) the free-flight time from thrust cutoff (t_tc-z) to Zenith and (b) the total free-flight time (t_ff)? (2 Points per Part)
8. What is the total horizontal distance (_x) covered by this rocket launch? (3 Points)he information and figure below, answer Questions 1-12 about a small
