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?

You throw a small rock straight up from the edge of a highway bridge that crosses a river. The rock passes you on its way down, 6.00 s after it was thrown. After the rock hits the surface of the water it sinks into the water through a depth of 1.0 meter and reached a speed of .5 m/s. What is the rate of slowing down for the rock in the water during this 1 meter travel, assuming it slows...
