Assume the three blocks (m1= 1.0 kg, m2 = 2.0 kg,, and m3 = 5 kg) portrayed in the figure below move on a frictionless surface and a force F = 48 N acts as shown on the 3.5 kg block.
- Determine the acceleration given this system (in m/s2to the right).
- Determine the tension in the cord connecting the 5kg and the 1.0 kg blocks (in N).
- Determine the force exerted by the 1.0 kg block on the 2.0 kg block (in N).
- What If?How would your answers to parts (a) and (b) of this problem change if the 0 kg block was now stacked on top of the 1.0 kg block? Assume that the 2.0 kg block sticks to and does not slide on the 1.0 kg block when the system is accelerated. (Enter the acceleration in m/s2 to the right and the tension in N.)
Since you have posted a question with multiple sub parts, we will provide the solution only to the first three sub parts as per our Q&A guidelines. Please repost the remaining sub parts separately
To calculate the acceleration of the system, the tension in the cord and the force exerted by the 1.0 kg block.
Given:
Mass of block 1:
Mass of block 2:
Mass of block 3:
Force on block 3:
To calculate:
1. The acceleration of the system:
2. The tension in the cord:
3. The force exerted by the 1.0 kg block on the 2.0 kg block:
According to Newton's second law of motion, the net force acting on a body is equal to the product of the mass of the body and the net acceleration produced by it.
where,
is the net force on the body,
is the mass of the body and
is the acceleration produced in the body.
