Question: Projectile Motion on an Incline IL Refer to Challenge Problem 3.89. (a) An archer on ground that has a constant upward slope of 30.00 aims

Projectile Motion on an Incline IL Refer to Challenge Problem 3.89.
(a) An archer on ground that has a constant upward slope of 30.00 aims at a target 60.0 m farther up the incline. The arrow in the bow and the bull's-eye at the center of the target are each 1.50 m above the ground. The initial velocity of the arrow just after it leaves the bow has magnitude 32.0 m/s. At what angle above the horizontal should the archer aim to hit the bull's-eye? If there are two such angles, calculate the smaller of the two. You might have to solve the equation for the angle by iteration-that is, by trial and error. How does the angle compare to that required when the ground is level, with 0 slopes?
(b) Repeat the above for ground that has a constant downward slope of 30.0o.
