monkey (m= 85kg) tries to cross a river by swinging from 10m long vine. His speed at the bottom of the swing as he just clears the water is 8.0 m/s. but the vine has a breaking strength of 1000 n. does he make it safely across the river and justify your answer
A monkey (m= 85kg) tries to cross a river by swinging from 10m long vine. His speed at the bottom of the swing
Centripetal force = mv^2/r
85*8^2/10 = 544 N
Force due to gravity = mg = 833 N
Total force at the bottom of the swing is 544 + 833 N %26gt; 1000
Wet monkey.
