Given :-

Mass of Elevator along its load = m = 800 Kg

Initial Velocity = u = 10 ms-¹

Heights travelled = h = 25 m

Acceleration due to gravity = g = 10 ms-².

Using third equation of Motion to find acceleration of the body.

v² = u² - 2ah

u² = 2ah

a = u²/2h

a = 100/50

a = 2 ms-².

{R}_{u} = m(g+a)

Let the tension R is acting in upward direction.

{R}_{u} = 800(10+2)

{R}_{u} = 9600 N
