## Homework Statement

Two masses M1 = 6.90 kg and M2 = 3.10 kg are on a frictionless surface, attached by a thin string. A force of 48.1 N pulls on M2 at an angle of 31.3° from the horizontal as shown in the figure. Calculate the tension T in the string.

## Homework Equations

T=ma

a=g(m2/(m1+m2))

## The Attempt at a Solution

a=g(m1/(m1+m2))

a=9.81m/s^2(3.10 kg /(6.90 kg + 3.10 kg))

a=9.81m/s^2(3.10 kg/10 kg)

a=9.81m/s^2(.31)

a=3.0411 m/s^2

T=ma

T=(6.90 kg)(3.0411 m/s^2)

T=20.98359 N
