Question

A rifle is aimed horizontally toward the center of a target100 m away. If the bullet strikes 10 cm below the center,what was the velocity of the bullet? (ignore air friction) A stone is thrown at an angle of 30 degrees above thehorizontal from the top edge of a cliff with an initial speed of 12m/s. A stop watch measures the stone's trajectory time fromtop of cliff to bottom to be 5.6 s. What is the height of hecliff? ( g=9.8 m/s^2 and air resistance is negligible) A rifle is aimed horizontally toward the center of a target100 m away.

Explanation / Answer

first question, not sure. Second question: t=5.6s v initial=12 m/s g=9.81 m/s^2 use equation y=1/2 gt^2 y=1/2 (9.81 m/s^2)(5.6s)^2 y=153.82m
