Physics string tension problem

Click For Summary
SUMMARY

The discussion revolves around a physics problem involving two blocks connected by a string over a frictionless, massless pulley. The hanging block has a mass of 16 kg, while the block on the inclined plane has a mass of 8 kg, with a coefficient of kinetic friction of 0.23 and an incline angle of 34 degrees. The user initially calculated the acceleration as 0.3967 m/s² and the tension in the string as 218.38 N. However, the correct acceleration is significantly higher, approximately 10 times the user's result, indicating a misunderstanding of the forces at play, particularly the gravitational force acting on the 16 kg block.

two blocks are connected by a strin over a frictionless, massless pulley suck that one is resting on an inclined plane and the other is hanging over the top edge of the plane. the hanging blcok has a mass of 16kg and the one on the plane has a mass of 8 kg. the coeficient of kineticfriction between the blck and the inclined pane is .23. the blocks are released from rest. the angle of the plane is 34 degrees.
what is the acceleration of the blocks
what is the tension in the string connectin ghte blocks
i got .3967 as the acceleration and 218.38 n as tension
any help thanks

The actual acceleration is about 10 times what you got.

If you think about it. The greatest accelerating force, from the 16kg block, would be 16g, which is about 160 N. Yet you got over 200 N as tension in the string. That would pull the 16kg block upwards !

How did you tackle this question ?

Could you show what work you did ?
