A man of mass m having a bag ofmas m slips from the roof of atall building of height H and starts falling vertically figure. When at a height h from the ground, he notices that the ground below him is pretty hard but there is a pond at a horizontal distnce x from the line of fall. In order to save himself he throws the bag horizontally (with respect to himself) in the direction opposite to the pond. Calculate the minimum horizontal velocity imparted to the bag so that the man lands in the water. If the man just suceeds toavoid the hard ground, where will the bag land?
