Two blocks of equal masses are connected by a string. Block 1 is pulled by a force of 30 N which accelerates both blocks at 3 m/s2 along a surface of negligible friction

A) find the masses of each block
B) find the tension

2 answers

a=force/masstotal
masstotal=30/3=10kg. If they are wqual, thekn each is 5kg

Tension in the first string is 30N, in the second, 15N (f=ma)
But If they were equal wouldnt each block weigh 10 kg
