Project motion of a model rocket When a model rocket is launched the fuel burns for a few seconds accelerating the rocket upward After burnout the rocket coasts upward for awhile and then begins to fall A parachute pops out shortly after the rocket starts down in order to slow the rocket Use the graph provided to answer the questions below Velocity m s 100 80 60 40 20 0 20 40 Time s 10 12 A Was the rocket going up or down 5 seconds after it was launched How do you B When did the rocket reach its highest point C Estimate the maximum altitude D Estimate the average velocity over the first 6 seconds E Compute exactly and give a practical interpretation of Tv t dt F Compute exactly and give a practical interpretation of v 8 G Find the average acceleration over the first 6 seconds
