Question

Two objects 3 kg and 4kg are connected by a pulley the object are inicially 5m from
find the acceleration of the system


please help me please please please ​

Answer 1

Answer:

a=33.6ms-2

Explanation:

» smaller mass = m1=3kg

» larger mass =m2=4kg

» Tension = T

» For mass m1

=> T−m1 g=ma ____eq(1)

» For mass m2

=> m2g−T=m2a. ____eq(2)

» By eq(1) + eq(2)

=> (m2−m1 )g = (m1+m2 )a

=> a=(m2 −m1 )g/(m 1+m2)

=> a=(4−3)×10/(4+3)

=>a=1×10/7=10/7

=> a=33.6ms −2
