				   A monkey is climbing up on a rope that goes over a smooth pulley and supports a block of equal mass at other end. Show that whatever force the monkey exerts on the rope, the monkey and the block move in the same direction with equal acceleration

6 years ago


Answers : (1)


Dear Sh Ha




Let the acceleration of monkey is a

for this acceleration to achieve by monkey it exerts a force T on the rope and  same reaction force is exerted by rope on the hand of monket

which cause monket to climb

So T-mg =ma


Now let the mass is acceleration by a'

force balance on mass


or  ma=ma'
