When a model rocket is launched, the propellant burns for a few seconds, accelerating the rocket upward. After burnout, the rocket coasts upward for a while and then begins to fall. A small explosive charge pops out a parachute shortly after the rocket starts down. The parachute slows the rocket to keep it from breaking when it lands. The figure here shows the velocity data from the flight of the model rocket. Use the data to complete parts (a) through (g). 200= 1505 100 50 0- -50 -100 4 Time after launch (sec) 10 12 velocity (ft/sec) to (g) When was the acceleration constant? Acceleration was constant between (Type integers or decimals. Round to one decimal place as needed.) and sec. What was the acceleration then? f/sec2 (Round to the nearest integer as needed.)
