a light sking pulley having two blocks of masses M1 and M2 if accelaration of system is 9 by 8 find ratio of two masses
JunaidMirza:
Are you sure that ratio given is 9/8?
*acceleration
yes
Ok. Then my answer should be correct
kk thanx

Acceleration of system is given as
a = [(m2 - m1) / (m1 + m2)]g
9/(8g) = (m2 - m1) / (m1 + m2)
9m1 + 9m2 = 80m2 - 80m1
89m1 = 71m2
m1/m2 = 71/89
Ratio of two masses is 71 : 89
a = [(m2 - m1) / (m1 + m2)]g
9/(8g) = (m2 - m1) / (m1 + m2)
9m1 + 9m2 = 80m2 - 80m1
89m1 = 71m2
m1/m2 = 71/89
Ratio of two masses is 71 : 89
