 The radius of a planet 2008-01-06 From Ben:Two people who are both h feet tall are standing on a spherical planet. One person walks a distance d in feet away from the the other person. At this point, the person walking turns around and can no longer see the top of the other persons head. What is the radius of the planet?Answered by Stephen La Rocque and Harley Weston. Computing gravity 2006-09-27 From Patricia:What is the gravity of planet z in inch/hr squared if the weight of an element with mass of 45000 oz on planet z is 2N?Answered by Stephen La Rocque. What is the radius of this planet 2005-08-05 From Kelly:Assuming that a North-South line has been established, you set up two camps that are 67 miles apart. You now set up poles at each camp perpendicular to the ground. On a certain day at "noon" the pole at the South camp casts no shadow, while at the North camp a shadow is cast. The shadow makes an angle of 89 degrees with the horizontal. What is the radius, diameter, and circumference of this planet?Answered by Chris Fisher. The radius of a planet 2001-07-30 From Jessica:A satellite is orbiting the earth at an altitude of 100 miles. If the angle of depression from the satellite to the horizon is 50 degrees, what is the radius (to the nearest mile) of the planet?Answered by Harley Weston.
