Tarzan

Tarzan, weighing m = 90 kg, tries to cross the river by swinging with a vine hanging from a tree leaning over the river. Liana has a length l = 12 m. The speed of the Tarzan in the lowest swing position is v = 8 m/s. Tarzan doesn't know that the liana will break when stretched with a force of F = 1000 N. Will Tarzan reach the other side of the river safely?
