I need simple solutions or ways to solve this questions...
3.87 ... Projectile Motion on an Incline. Refer to the Bridging
Problem in Chapter 3. (a) An archer on ground that has a constant
upward slope of aims 30 degree 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’seye?
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 slope? (b) Repeat the
problem for ground that has a constant downward slope of 30 degree
Explanation / Answer
I don't understand this phrase: "An archer on ground that has a constant
upward slope of aims 30 degree at a target 60.0 m farther up the
incline. "
Where is the archer and where is the bull? Is the arrow going upward the incline or downward?
"Repeat the
problem for ground that has a constant downward slope of 30 degree." Does it mean that the arrow is going downward the same incline this time?
Please, clarify the situation(s) and I'll solve the problem.
