The rope pesses over an kleal (frictionless and massiess) pulley such that one block with mass m 12.35 kg is on a borizontal table and the other block with mass mo-6.5 kg hangs vertically.

Explanation / Answer

here,

a1 = T/m1

a1 = T/12.35 .....(1)

b)

for m2

accelration be a2

m2 * a2 = m2 * g - T

a2 = ( m2*g - T)/m2

a2 = ( 6.5 * 9.81 - T)/6.5 .....(2)

c)

as both blocks are connected by same rope and the pulley is masseless

the accelration is same

a1 = a2 ....(3)

from (1),(2) and (3)

a1 = a2 = 3.38 m/s^2

T = 41.8 N

d)

the tension in the string is 41.8 N
