You fire a ball with an initial speed vo at an angle Ø above the surface of an incline, which is
itself inclined at an angle 0 above the horizontal (see figure).
(a) Find the distance, measured along the incline, from the launch point to the point when
the ball strikes the incline.
(b) What angle Ø gives the maximum range, measured along the incline?

(a) If you leave the bank of the river at an angle 0 = 30°, what initial speed do you
need to just barely make it to the other side?
(b) If you jump at this angle and with the speed you found in (a), what is your speed
just before you land on the other side of the river?
(c) Suppose that when you land on the other side of the fiver, an average force of
14 000 N brings you to rest. Assuming all of this force is exerted on your tibia, what is the percent
change in the length of your tibia as you are landing? Assume the tibia has a cross-sectional area
of 3 cm? and a Young's modulus of 1.4 x 1010 Pa.
An item with beginning speed vo is projected from the edge of the
roof of a structure of height H. The object's initial velocity produces
an angle a0 with the horizontal. Don't think about air resistance.
What is the speed of the item shortly before it hits the ground if a0 =
-90 and the object is thrown straight down?
