Black vultures excel at gliding flight; they can move long distances through the air without flapping their wings while undergoing only a modest drop in height. A vulture in a typical glide in still air moves along a path tipped 3.5° below the horizontal. If the vulture moves a horizontal distance of 100 m, how much height does it lose?
Problem 2:
In baseball the pitcher will throw baseballs horizontally and to account for gravity, the
pitcher will stand upon a raised mound. Take the pitcher's release point to be 1.2m above
the ground and they will hit a spot 0.7m above the ground at a distance 20m away.
a)
Draw ST vs t, sy VS t, Uz VS t,, Vy vs t, a vs t,, and ay vs t, graphs of
the baseball's motion
b)
from Kinematic Equations on the first page
Prove that the velocity needed is =
9(Asz)²

c)
If the pitcher was playing on Mars (g = 3.7m/s, negligible air resistance)
how fast would they have to pitch?
The figure shows the path taken by a drunk skunk over level ground, from initial point i to final point f. The angles are 0, - 32.0°,
e2 = 49.0°, and e3 = 84.0°, and the distances are d= 4.80 m, d2 = 7.30 m, and d3 = 10.0 m. What are the (a) magnitude and (b) angle of
the skunk's displacement from i to f? Give the angle as a positive (counterclockwise) or negative (clockwise) angle of magnitude less
than 180°, measured from the +x direction.

- The 1994 Winter Olympics included the aerials competition in skiing. In this event skiers speed down a ramp that slopes sharply upward at the end. The sharp upward slope launches them into the air, where they perform acrobatic maneuvers. In the women's competition, the end of a typical launch ramp is directed 59° above the horizontal. With this launch angle, a skier attains a height of 14 m above the end of the ramp. What is the skier's launch speed?arrow_forwardThe figure shows the path taken by a drunk skunk over level ground, from initial point i to final point f.
