Question

1. If m, 10kg, m,-4kg, m=2 kg, the
acceleration of system is​

Answer 1

$\tt \boxed{ \fcolorbox{red}{pink}{ANSWER }}$

Three blocks of masses M1 M2 and M3 And the strings to each their connected are massless Total mass of the system is given as 20 kg .And the force applied is given as 40 Newton so by applying the equation for sequel to mass into acceleration we can find the acceleration of the system a = 40/20 = 2 metre per second square T2 is pulling the blocks M1 and M2 hence the tension in string T2 will be (m1 +m2) a = 32 N
