A rock is dropped into a river from the top of a mountain. It starts from rest and falls freely and vertically. Using the four generic kinematics equations listed below, provide your simplified equations using a coordinate system whose y axis is positive down and the x axis positive right such that the origin is located at the top of the mountain.

A rock is thrown vertically downward from the edge of the
mountain. It leaves your hand at a point even with the edge and a
speed of 15 m/s. Using the four generic kinematics equations listed
below, provide your simplified equations using a coordinate system
whose y axis is positive down and the x axis positive right such
that the origin is located at the edge of the mountain.

A rock is thrown vertically upward from the edge of a cliff. It
leaves your hand at a point even with the edge at a speed of 25
m/s. The rock is then in free fall. On its way back down, it misses
the edge of the cliff and continues its fall towards the river.

A hot-air balloon rises at a velocity of 10 m/s. When the
balloon is 60 meters above the ground, it releases a sandbag. After
release, the sandbag is in free fall. Using the four kinematics
equations listed below, provide your simplified equations using a
coordinate system whose y axis is positive up and the x axis
positive right such that the origin is located at the ground
level

You throw a rock with an initial speed of 30 m/s and an angle of 50 degrees with respect to the vertical. The field you are on is however not horizontal but is inclined by an angle of 10 degrees with respect to and above the horizontal. Choose a coordinate system whose origin is located where the rock is thrown, and a rotated system such that the positive y axis is positive at an angle of 100 degrees measured counterclockwise...

A rock is dropped from the top of a vertical cliff and takes 3.00 s to reach the ground below the cliff. A secon rock is thrown vertically from the cliff, and it takes this rock 2.00 s to reach the ground below the cliff from the time it is released. With what velocity was the second rock thrown, assuming no air resistance? Select one: a. 5.51 m/s downward , b. 4.76 m/s downward X O c. 12.3 m/s downward...

You toss a ball from your window 14 meters above the ground. When the ball leaves your hand, it is moving at a speed of 20 m/s at an angle of 10 degree below the horizontal. Choosing a coordinate system such that its origin is located on your hand, the positive x axis is down and the positive y axis is right. Provide all the simplified equations of motion in both directions for this projectile motion problem.
