Question

A man of mass 20 kg uses a rope to climb which bears only 440 Newton. what is the maximum acceleration with which he can climb safely.​

Answer 1

Explanation:

Correct option is

A

15

Since,

force=massxacceleration

so, 450=30xacceleration

or acceleration =15m/s

2

Hence,

option A is correct answer.

Answer 2

Answer:

Mass of man = 20kg

Max. Force = 440 N

Now ,

Since. , F = m.a

So , 440=20.a

=> a = 440/20 = 22 m/s

Explanation:

So , the maximum acceleration with which he can climb the rope safely is 22m/s . [ Answer ]

* If he climbs with an acceleration more than 22m/s , then the rope will break.
