Question

find the acceleration of body of mass 2kg from the figures shown

Answer 1

T = tension in the string

m₁ = 2 kg

m₂ = 3 kg

a = acceleration

using the force diagram , force equation for m₂ is given as

m₂ g - T = m₂ a

T = m₂ g - m₂ a                           eq-1

using the force diagram , force equation for m₁ is given as

T - m₁g = m₁a

using eq-1

m₂ g - m₂ a - m₁g = m₁a

a = (m₂  - m₁)g/(m₂ + m₁)

inserting the values

a = (3 - 2)(9.8)/(3 + 2)

a = 2 m/s²
