Homework Answers
Here, we have been given height h above the surface as 10 m
We have also been given the distance to horizon (d) (straight line) as 5895 m
we need to find the radius of moon
therefore, we can use Pythagoras theorem
d2 = (R+h)2 - R2
d2 = R2 + 2Rh + h2 - R2
d2 = 2Rh + h2
58952 = 20R + 100
R = 1737546.25 m
R = 1737.55 Km
or
R = 1738 Km

Deep in the physics and astronomy basement storeroom, you find a very large concave spherical mirror from an old telescope. The mirror is 2 m across, and has a radius of curvature of 14.0 m. Because this is just a small piece of such a large sphere, the angle of incidence for on-axis rays will always be below 5°, minimizing spherical aberration You try out the mirror for use as a full-length wall mirror. If you look at yourself in...

A 1.85 m tall basketball player attempts a goal 14.03m from the basketball hoop, which is at the height of 3.05 m. The acceleration of gravity id 9.81 m/s^2. If he shoots the ball at an angle of 46.0 degree, at what initial speed must he throw the basketball so that it goes through the hoop without striking the board? What is the time required for the ball to reach its maximum height? Determine the maximum height reached by the...
