A projectile is shot at an angle of #pi/4 # and a velocity of # 21 m/s#. How far away will the projectile land?
The projectile will land 45 m downfield, assuming it was launched over level ground.
Rather start from scratch (meaning the equations of motion) to solve this one, I will use an equation that can be derived for the range
Now it is a simple matter of putting values in place of variables:
