- Homework Statement
- In the given figure if acceleration of Mass M with respect to ground is a then, find the acceleration of mass, m with respect to incline and with respect to the ground in terms of 'a'

- Relevant Equations
- T - Tcosα + Nsinα = Ma

mgsinα - T = ma

N = mgcosα

This was the question:

But I could not solve the equations to find the answer. I realise with respect to inclined plane the acceleration must be a since string cannot slack. With respect to ground, the acceleration of incline is added.

However, I could solve the force equations to get required acceleration. Other answers seem to ignore the effect of tension on the pulley due to pulley and use the former method.

I derived the equations as mentioned in the relevant equations.I derived the equations as mentioned in the relevant equations.

*What is the acceleration of the string in the ground frame? In the frame of the incline the acceleration on either side of pulley is equal and string does not slack.*

**In the ground frame, the string on the side of the block will get an horizontal component of acceleration but the fixed end of the string will have same acceleration. This implies the string should slack which it does not. So where is my mistake?****How do I solve the problems using the force equations I derived?**

Are my force equations correct.Are my force equations correct.
