Question

2 blocks of m 10 and 10kg are
connected. A F applied on the
upper string produces an
acceleration of 5m/s2 in the
upward direction. Find T & T'​

Answer 1

Answer:

T = 296 N,

and T' = 148 N

Explanation:

mass 1 = 10 kg

mass2 = 10 kg

acceleration = 5 m/sec

Force = F

Lets assume two blocks like one

so the equation of the motions of combination is = f ( m1 + m2 )g = ( m1 + m2) a

T= ( m1 + m2) ( g + a )

by putting values,

T = ( 10 + 10 ) ( 9.8 + 5 )

= ( 20 ) ( 14.8 )

=296 N

and

T' = m( g + a)

= 10( 9.8 + 5 )

= 10( 14.8 )

= 148 N
