Question

Two bodies of masses 4kg and 5 kg are acted upon by the same force.if acceleration of lighter one is 2m/s^2 then the acceleration of the heavier one is

Answer 1

body of mass 4 kg and 5 kg are acted upon by the same force.

m1 = 4 kg
a1 = 2 m/s^2

m2 = 5kg
a2 = ?

Since force is same,

Force = m1 × a1 = m2 × a2

=> 4 × 2 = 5 × a2

=> a2 = 4×2 / 5 = 8/5 m/s^2 = 1.6 m/s^2

Force = m1 × a1 = m2 × a2

=> 4 × 2 = 5 × a2

=> a2 = 4×2 / 5 = 8/5 m/s^2 = 1.6 m/s^2
