Question
There are three blocks connected by strings as shown in the figure. Each block has the mass as following mass,
m1=1.0kg
m2=2.7kg
m3=2.0kg
Assuming there is no friction,
(a) Find the acceleration of the blocks
(b) Find the tension of the string between m2 and m3
Explanation / Answer
a) m3g = (m1+m2+m3) a
=> a = [m3 /(m1+m2+m3)] g = 3.44 m/s^2
_________________________________________
b) m3g - T = m3 a
=> T = m3 (g - a)
= 2 (9.8 - 3.44)
= 12.72 N
