What is the ? Yes, I know it is a typo. But if you are too lazy to proofread your posts BEFORE you click on SEND, why should any of us exert any effort at all to help you?



is the almost proper function. I say almost because using as the value for one-half of the acceleration due to the gravitational force near the surface of the earth gives much more precise answer. Be that as it may, solve



for both values of
