Projectile Motion - 103
BlackBoard Notes

======================= Photo - Click for a Larger Version =============================

======================= First Board Section =============================

• What is the initial velocity of the projectile?

Theory:

• Trash can shot scoring & rules:
  • Sink ball on first shot: +5 pt.
  • Bonus: Juice can (w/different θ): +1 pt.
    • ONLY if sufficient time!
  • No practice shots!
  • I must witness your shot!

======================= Second Board Section =============================

x = x_o + v_oxt + ½a_oxt²           {#1}

y = y_o + v_oyt + ½a_oyt²           {#2}

Which quantities are known? Unknown?

x = d	y = 0
xo = 0	yo = h
vox = ?	voy = 0
aox = 0	aoy = –g
t = ?	t = ?

======================= Third Board Section =============================

Simplify:

{From #2}		{From #1}

======================= Fourth Board Section =============================
