Question

In the figure shown, find acceleration of the system and Tensions T,,T, and T, [g = 10 m/s?]
a) 4m/s2, 24 N, 42 N, 14 N

b) 3m/s?, 24 N, 43 N, 14 N

c) 4m/s2, 24 N, 43 , 14 N

d) 4m/s2, 24 N, 42 N, 20 N​

Answer 1

Answer:

a) 4m/s2, 24N, 42N, 14N

Explanation:

Consider m1=4kg m2=3kg m3=2kg m4=1kg

a=(m1+m2)-(m3+m4)/m1+m2+m3+m4×g

a=4m/s2

T1=m1g-m1a

T2=(m1+m2)g-(m1+m2)a

T3=m4g+m4a
