Apilot isinaplanemoving at100m/shorizontally.Hethrowsawaterballoonwithaninitial velocityof8m/s directly downwards. The balloon hits the ground 15 seconds later.
- Drawaprojectilemotionmapofthesituationonthatincludes anymeasurementsandthepathofthe balloon,includingvelocityandaccelerate onvectorsforboththehorizontalandverticaldirection.
- Determine if the system is balanced or unbalanced, draw a force diagram, construct an x/y table of equations, and make a net force equations on for the balloon while it's in the air. Assume air resistance is negligible.
