5.50 ppt batfink angle launched projectile motion

  1. 1. Ebeneezer the Freezer<br />
  2. 2. Rules of This Activity<br />#1 All students must perform all of the work of the activity in their science journals even though you are working in your lab group.<br />#2 When you are sure of your answer, transfer the information onto a large whiteboard.<br />#3 The whiteboard work is to remain on the white board until it is approved. <br />
  3. 3. The Problem<br />Ebenezer the Freezer and Hugo A-Go-Go strap Batfink to a rocket.<br />Batfink emits a “BEEP” from his supersonic sonar radar that calculates the displacement the rocket will have at impact with the ground.<br />The rocket is launched at an angle of 30* to the horizontal and fortunately the rocket is faulty and only has a velocity of 39.2 m/s. <br />
  4. 4. Working the Problem<br />Draw a Motion Map for the rocket’s motion.<br />
  5. 5. Motion Map<br />
  6. 6. Working the Problem<br />Resolve the initial velocity into two vector components, one moving the rocket horizontally and one vertically.<br />Show all of your work.<br />
  7. 7. Resolve the initial velocity into “x” and “y” components<br /> y <br />33.95 m/s = (Vx) 19.6 m/s <br /> 30* x<br />SOH CAH TOA 33.95 m/s <br />SIN 30* = Vy/V <br />(39.2 m/s)(0.5) = (Vy)<br />19.6 m/s = (Vy)<br />SOH CAH TOA<br />COS 30* = Vx/V <br />(39.2 m/s)(0.866) = (Vx)<br />
  8. 8. Working the Problem<br />Calculate the time the rocket will spend in the air.<br />
  9. 9. Calculate the time the rocket will spend in the air.<br />Know Want<br />Yf= 0 m t<br />Yo= 0 m<br />Vo = 19.6 m/s<br /> a = -9.8 m/s2<br />General Formula Yf = Yo + Vot + ½ at2<br /> 0 = 0 + (19.6 m/s)(t) + ½ (-9.8 m/s2 )(t2)<br /> (19.6 m/s)/-4.9 m/s2 = t <br /> 4 s = t <br />
  10. 10. Working the Problem<br />Calculate the “Xf” distance and the “∆Y” distance that the projectile will travel.<br />
  11. 11. Working the Problem<br />Horizontal Distance <br />X = Vx(t)<br />X = (33.9 m/s)(4 s)<br />X = 136 m<br />Vertical Distance<br />Y = Vy(t) + ½ gt2<br />Y = (19.6 m/s)(2s) – ½ (-9.8 m/s2)(2s2)<br />Y = 19.8 m<br />
  12. 12. Working the Problem<br />Construct and complete a Data Table with the first column being time (s), the second column distance (x) and the third distance (y).<br />
  13. 13. Construct a Data Table<br />
  14. 14. Working the Problem<br />Graph the path of the projectile, distance “Y” over distance “X”.<br />
  15. 15. Graph the path of the projectile, distance “∆Y” over distance “X”.<br />19.6<br />Distance Y (m)<br />14.7<br />33.9<br />67.8<br />102<br />135.8<br />Distance X (m)<br />
