Question

Three blocks, are connected by string as and are pulled by a force T3=120N. If m1=5 kg, m2=10 kg and m3=15 kg. Calculate the acceleration of the system and T1 and T2??

Answer 1

$\textbf{Answer...}$

==>1) Acceleration of the system a = F/m1+m2+m3 = 120/5+10+15 = 4m/s^2

==>{ 2) T1 = m1a = 5×4 = 20 N T2=( m1+m2)a = (5 + 10)4 = 60 N

$\textbf{Hope it helps u}$✌

Answer 2

==>1) Acceleration of the system a =
F/m1+m2+m3 = 120/5+10+15 = 4m/s^2

==>(2) T1 = m1a = 5×4 = 20 N T2=(
m1+m2) a = (5+10)4 = 60 N
