Question

heyyy guys..

a monkey is descending from a branch of tree with constant acceleration.if the breaking strength of the branch is 75% of the weight of Monkey then the minimum acceleration with which the monkey can slide down without Breaking the branches is..



the ans is g/4..explain how..

Answer 1

As monkey is descending

let m be mass of monkey

T be tension

a be acceleration

So

mg - T = ma

Now here breaking strength is given that is maximum tension

As mg - T = ma

So if T is maximum and u are subtracting it with mg it would give least value of ma that is minimum acceleration

T = 75 % of mg

so mg - 75% of mg = ma

25% of mg = ma

mg/4 = ma

g/4 = a

Answer 2

let the force developed in the branch that will not let the branch to be break be F.
