| **The breaking strength of the rope is 1600 N. What is the maximum mass of the load that can be lifted with this rope with an acceleration of 15 m / s ^ 2.**

Given:

T = 1600 Newton – tensile strength of the rope;

a = 15 m / s ^ 2 – acceleration;

g = 10 m / s ^ 2 – acceleration of gravity.

It is required to determine the mass m (kilogram) of the load that can be lifted by this rope with acceleration a.

According to Newton’s second law:

T – F gravity = m * a;

T – m * g = m * a;

T = m * a + m * g;

T = m * (a + g);

m = T / (a + g) = 1600 / (10 + 15) = 1600/25 = 64 kilograms.

Answer: with the help of this rope with an acceleration of 15 m / s ^ 2, you can lift a maximum load equal to 64 kilograms.
