You will begin with a relatively standard calculation. consider a concave spherical mirror with a radius of curvature equal to 6 0.0 centimeters. an object 6.00 centimeters tall is
1 answer:
We are given a concave spherical mirror with the following dimensions: Radius = 60 cm; D o = 30 cm Height = 6 cm; h o = 6 cm First, we need to know the focal length, f, of the object (this should be given). Then we can use the following formulas for calculation: Assume f = 10 cm 1/ f = 1 /d o + 1 / d i 1 / 10 = 1 / 30 + 1 / d i d i = 15 cm Then, calculate for h i: h i / h o = - d i / d o h i / 6 = - 15 / 30 h i = - 3 cm Therefore, the distance of the object from the mirror is 3 centimeters. The negative sign means it is "inverted".

Replace y with 0 and you get x = -5.511, and x = 5.511, since time has to be positive, it takes approximately 5.51 seconds for the stone to hit the ground.
