$(1$ point$)$ in an Atwood machine one block has a mass of $M_1=600g$ and the other has a mass of $M_2=400g$ The frictionless pulley has a radius of $75$ cm When released from rest the heaver block moves down $54$ cmi in $1\mathrm{.}75$ s $($no slippage$)$

What is the magnitude of the acceleration of the lighter block?

$$

What is the tension $T_1?$

What is the magnitude of the angular acceleration of the puiley?

Find the pulley's moment of inertia
