Two masses, m 1 =380 kg , and m 2 =245 kg , initially at rest on a horizontal frictionless surfaceare tied together by a string(Shown above.) A force is applied to the right of m 2 of 156 N and is 20 degrees above the horizontal . What is the acceleration of m 2 , and what is the tension ( T) in the string that is connecting the two masses ?
