**Multiple Pulleys!!**

## Homework Statement

A 60 kg mass and a 10 kg mass are attached together by massless inextensible strings which pass over light frictionless pulleys. One pulley is free to move while the other is fixed.

a) The system is initially held at rest by means of a force supporting the 60 kg mass. Calculate the magnitude of the tensions T1 and T2.

b)When the system is released. calculate the magnitude of

1)Tension T1 ans T2

2)Aceeleration of the 10 Kg

3) Acceleration of the 60 Kg

Here is the diagram if it helps:

## Homework Equations

Depends.

## The Attempt at a Solution

I tried solving this for part a:

For Ti i did:

Fg=T1

mg=T1

(10kg)(9.8 m/s^2)=T1

98 N=T1

for T2:

Fg=T1+T2

mg=T1+T2

(60kg)(9.8m/s^2)-98N=T2

490 N=T2
