Final answer:
To find the acceleration, the net force caused by the difference in the weights of the two buckets is divided by the total mass of the system. The acceleration due to gravity is factored into the calculation as 1.783m/s².
Step-by-step explanation:
The question involves finding the acceleration of a system with two buckets of different masses connected by a massless rope going over a frictionless pulley.
Considering the masses m₁ = 21.5 kg (descending) and m₂ = 14.9 kg (ascending), Newton's second law can be applied to find the net force and therefore the acceleration of the system.
Let's denote the acceleration of the system as a.
The net force on the system causing the acceleration is the difference in the weights of the two buckets: (m₁- m₂)g, where g is the acceleration due to gravity, roughly 9.81 m/s².
Both masses are accelerated, so we use the total mass of the system (m₁ + m₂) to find the acceleration:
Net force = (m₁ - m₂)g = (m₁ + m₂)a
Solving for a, we get a = (m₁ - m₂)g / (m₁ + m₂)
Plugging in the values:
a = ((21.5 kg - 14.9 kg) * 9.81 m/s²) / (21.5 kg + 14.9 kg)
a≈1.783m/s²
This gave us the acceleration of the system.
Two buckets of mass m1= 21.5 kg and m2=14.9kg are attached to the end of a massless rope which passes over a pully with a mass of mp=9.73 kg and a radius of r=0.150 m. The system is set up in such a way that the rope is wound around the pulley. The pulley is assumed to be an ideal pulley (massless and frictionless). Let's assume that bucket m 1 is initially higher than bucket m 2 and that the system is released, allowing m 1 to descend and m 2 to ascend. Let's assume that the pulley is frictionless, and there is no friction between the rope and the pulley. Let's assume that the system is initially at rest, meaning that m 1 is held in place and m 2 is suspended. find the acceleration?
