22. Calculations
y1 = (-m/2k)*ln ((T-mg-kv2)/ (T-mg))  ( / (2*.00154))*ln (( (91.762))/ ( )) = *ln (.792) = 28.95
yc = (m/2k)*ln ((mg+kv2)/ (mg))  (.38125/(2*.00154))*ln( )/( )) = *1.496) =  
ta = (tan-1(v/qa))/qb  (tan-1(91.676/49.256))/.199 = 1.861/.199 = sec
y1 + yc = total altitude  = m = feet

26. Test Results Durability Test Criteria How Tested Expected results
Actual Results
 Safety
 Check signs of unsafe damage
 Rocket remains intact
The rocket flew safely during all 5 tests.
Durability  
 Check for signs of deterioration
 Be ready to fly again
Had to be repaired 3 times after test flights
 Parachute
 Check for rips or holes
 No tears, still attached
Remained intact
 Altitude 
 Read altimeter after each test flight
 725 and 775 feet
Reached target altitude 0/5 tests.
 Flight Consistency
Time each flight
 Flight be between seconds
Within time constraints 1/5 tests (too short)
Explain test plans here instead of making a pointless slide for them
