Question

Two blocks, the first with a mass of 30 kg, and the second 10kg, are connected by a string and pulled accross a frictionless surface by a force with a magnitude of 75 N. Find the magnitude of the tension acting along the string that connects them.

Answer 1

Which block is being pulled by the string?

First, get the accleration rate of both using

F = 75 N = (30 + 10)*a

Use that acceleration rate to get the tensjon in the string.

Answer 2

I don't know please help
