Hello guys, in this problem, we have a platform and on the platform we have a person standing over this platform.
00:11
The platform is attached with a rope, the rope passing over a frictionless pulley, and the other end of the rope is being pulled by the person.
00:25
It is given that the mass of the person, m1 and the mass of the platform is emptied.
00:31
The mass of the person given is 80 kilograms and the mass of the platform given is 40 kilograms.
00:40
A force is being exerted by the person on the rope.
00:45
Let's suppose the force is f, such that the system accelerate upward with uniform acceleration a where the uniform acceleration is 1 meters per second square.
00:57
We need to find out the force f.
01:00
When the person exert the force f, the reaction force exerted by the robe on the person will also be f, that is the tension force...
