Laws Of Motion Question 320
Question: . One end of a massless rope, which passes over a massless and frictionless pulley P is tied to a hook C while the other end is free. Maximum tension that the rope can bear is 360 N. With what value of maximum safe acceleration (in$ m{{s}^{-2}} $ ) can a man of 60 kg climb on the rope?
Options:
A) 16
B) 6
C) 4
D) 8
Show Answer
Answer:
Correct Answer: C
Solution:
[c] $ mg-T=ma $
$ \therefore a=g-\frac{T}{m}=10-\frac{360}{60}=4m/s^{2} $
