Question

A man of mass 30 kg uses a rope to climb which bears only 450 N. What is the maximum acceleration with which he can climb safely? ( Ans: 15 m/s² )

Answer 1

Given,
Mass=30kg
Force=450N
as we know,
force=mass×acceleration
450=30×a
450=30a
a=450/30
a=15m/s^2 (Ans)

Answer 2

Answer:

The maximum acceleration with which the man can climb safely is 15m/s².

Explanation:

Given:

Mass(m) = 30kg

Force(F) = 450N

To find:

Acceleration(a) =?

Formula:

Force = Mass × Acceleration

Solution:

We know that force is given as the product of mass and acceleration.

Here, the mass of the man is given to be 30kg, and the rope can bear up to 450N.

Substituting the given values in the above formula, we get

Force = Mass × Acceleration

450 = 30 × a

a = 450/30

a = 15

Acceleration = 15m/s²

Therefore, the maximum acceleration is 15m/s².
