Bubba sees a bird sitting on a branch. He throws a rock at the bird. The rock is thrown at a velocity of 6.45 m/s and an angle of 50.1º with respect to horizontal. The bird is sitting on a branch a distance of 0.877 meters above Bubba's hand and 2.02 meters horizontally from his hand. How high above or below the bird does the rock pass?

A child standing on the edge of a sheer cliff wall throws a rock down towards the ground below. The rock is thrown 27° below the horizontal at a speed of 14m/s & lands 13 m from the base of the cliff wall. Ignore air drag. A.) Determine how long the rock was in the air. B.) Determine how high the cliff wall is. C.) Determine how fast the rock was going upon impact. D.) Determine the angle of impact....

A rock is thrown off a cliff at an angle of 51° above the horizontal. The cliff is 130 m high. The initial speed of the rock is 20 m/s. (Assume the height of the thrower is negligible.) (a) How high above the edge of the cliff does the rock rise (in m)? (b) How far has it moved horizontally when it is at maximum altitude (in m)? (c) How long after the release does it hit the ground (in s)? (d) What is...

A catapult on a cliff launches a large round rock towards a ship
on the ocean below. The rock leaves the catapult from a
height
33.5 m above sea level, directed at an angle
48 degrees above the horizontal, and with a speed
24.7 m/s. Assuming that air friction can be neglected, calculate
the horizontal distance traveled by the projectile.
