Tbl'"fall"d1vtded by the boriz r ts the tangent of down angle. Use )OUr scienhfic calculator to determme the down angle, tan 1
the tangent number calculated. Now take the cosme of this angle. The slant
,sl r, is the horiz r divided by cos(dwn angle). Bullet night time is sl r divided bullet velocity= t. Use the Air resistance info abovl' for bullet velocity. The additional fall oftbe bullet on the path due to gravity is 16.1(t)2• So the shooter had to aim a:bit high for the bullet to arrive where it did, sin-1

C)check height along path
