A monkey is descending from the branch of a tree with a constant acceleration. If the breaking strength of the branch is 75% of the weight of the monkey, the minimum acceleration with which the monkey can slide down without breaking the branch is
Let the weight of the monkey=mg
So,the strength of the branch=75%of mg=3/4*mg
Since the net acc.is in the downward direction so
mg-3/4*mg=ma
=> g-3/4*g= a
=>a=g/4.
So the minimum acc.is g/4.
