The sement bag has a mass of 50 kg an the small pulley has a mass of 2kg ,if the cement bag pulled upwards with an acceleration of 2m/s.fin the force pulling the rope
Need to know how the rope is configured...i.e. the mechanical advantage

To find the force pulling the rope, we can use Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration.
In this case, the net force is the force pulling the rope, and the mass of the object is the combination of the cement bag and the small pulley.
Step 1: Calculate the total mass:
The total mass is the sum of the masses of the cement bag and the small pulley:
Total mass = mass of cement bag + mass of small pulley
= 50 kg + 2 kg
= 52 kg
Step 2: Calculate the force pulling the rope:
Using Newton's second law, we have:
Net force = total mass * acceleration
Force pulling the rope = total mass * acceleration
= 52 kg * 2 m/s^2
= 104 N
Therefore, the force pulling the rope is 104 Newtons.
