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 $(g)$. (D) ror now marry seconos aid une engine burile $\sec$ (Type an integer or a decimal. Round to one decimal place as needed.) (c) When did the rocket reach its highest point? $\sec$ (Type an integer or a decimal. Round to one decimal place as needed.) What was the rocker's velocity when it reached to its highest point? ftisec (Round to the nearest integer as needed.)
