Question

Drop-load (I)

Context

We want to lower a suspended load in a controlled way so that it hits the ground with a speed whose modulus is not too great. To do this, the suspended load (B) is connected by a rope passing through a pulley to another mass (A), which can move on a horizontal surface.

Information

The masses of the charges A and B are known.
The pulley is a ring of mass mp and radius R that can rotate without friction.
The surface on which mass A is placed is horizontal.
There is no friction between mass A and the surface on which it is placed.
The string attached to mass A is perfectly parallel to the surface on which the mass rests.

Modelization

Create a model for the acceleration of mass B given the known parameters of the problem that are relevant.

 

Mass of the load A: 80kg;

Mass of suspended load (B): 71kg;

Pulley mass (mp): 55kg

Pulley radius: 0.64m
