Do first – ensure your calculator is in degree mode, retrieve yesterday’s handout (1-19).Today we will learn how to solve projection problems with _______________________________.ScenarioStopping pointAn object is launched from the ground and lands on the groundAn object is launched, what is the highest point reached?An object is launched, what is its (height/ speed) at (fill in the blank) point in time?An object is projected at an angle and hits a building z meters awayAn object is projected at an angle and flies for 5 seconds before striking a building/cliffA note about calculating final speed:Practice defining ending points for the following problemsScenarioEnding pointDiagram-an object is launched horizontally off of a cliff that is 70 meter high and lands on the ground.-an object is thrown from a cliff at an angle and lands on the ground. an object is launched and lands at an unknown height 4.2 seconds later. an object is launched from the ground at a building 20 meters away. an object is launched from the ground and lands on top of a building that is 10 meters tall. An object is launched at an angle, what is the highest point reached by the object?Practice problems: On a separate paper, for each problem, determine the final vertical displacement (dy), total time, the total horizontal distance travelled, the final speed and the highest pointAn object is launched with an initial speed of 45 meters per second at 40° and lands at an unknown height 4.2 seconds later. final vertical displacement (dy)= total time= total horizontal distance travelled= final speed highest point=An object is launched horizontally at 20 m/s off of a cliff that is 70 meter high and lands on the ground. final vertical displacement (dy)= total time= total horizontal distance travelled= final speed highest point=An object is launched from the ground with an initial speed of 55 m/s at an angle of 80° and lands on top of a building that is 10 meters tall.final vertical displacement (dy)= total time= total horizontal distance travelled= final speed highest point=An object is launched from the ground at an initial speed of 100 m/s at an angle of 20° toward a building 20 meters away.final vertical displacement (dy)= total time= total horizontal distance travelled= final speed highest point=An object is thrown from a 45 meter high cliff at an initial speed of 10 meters per second and an angle of 40° and lands on the ground. final vertical displacement (dy)= total time= total horizontal distance travelled= final speed highest point= ................
