Astone is tied to a string (length 1.10 m) and whirled in a circle at the same constant speed in two different ways. first, the circle is horizontal and the string is nearly parallel to the ground. next, the cir- cle is vertical. in the vertical case the maximum tension in the string is 15.0% larger than the tension that exists when the circle is horizontal. determine the speed of the stone.'

v = 1.27 m/s

Explanation:

When stone is moving in horizontal circle with constant speed

then in this case the centripetal force is given as

Now when stone is moving in vertical circle then we will have

now we know that

double the distance = divide strength by 4

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
