# Three blocks of masses 1.0, 2.0, and 4.0 kilograms are connected by massless strings, one of which passes over a frictionless pulley of negligible mass, as shown above. Calculate each of the following. 

Three blocks of masses \( 1.0 \, \text{kg} \), \( 2.0 \, \text{kg} \), and \( 4.0 \, \text{kg} \) are connected by massless strings, one of which passes over a frictionless pulley of negligible mass, as shown above. Calculate each of the following.

**Part a)** The acceleration of the 4-kilogram block. Solve as a system. *(3 points)*

**Part b)** The tension in the string supporting the 4-kilogram block. *(3 points)*

**Part c)** The tension in the string connected to the l-kilogram block. *(3 points)*
