Rock thrown off a cliff
You want to know the height of a cliff so you throw a rock off the
edge with an initial speed of 18.5 m/s inclined at an angle 30.3°
above the horizontal. You have a friend that records that it takes
3.4 s for the rock to hit the bottom of the canyon after it is
thrown. For the following questions, call up the positive
y direction and make the positive x direction
horizontal and towards the direction the rock is thrown.
If you ignore air resistance, what is the x component of
the velocity of the rock right before it hits the ground?
