a resultant force of 20N gives a body of mass and acceleration of 1m/s²
from Newton's 2nd law, F = ma
so, 20 = × 1 m/s²
= 20kg......(1)
again, 20N acts on a body of mass M and acceleration 24m/s²
so, 20 = M × 24
M = 20/24 = 5/6 Kg
now, when two masses combine together
F = (M1 + M) a'
20 = (20 + 5/6) × a'
20 = (125)/6 × a'
4 = 25/6 × a'
a' = 24/25 m/s²
from Newton's 2nd law, F = ma
so, 20 = × 1 m/s²
= 20kg......(1)
again, 20N acts on a body of mass M and acceleration 24m/s²
so, 20 = M × 24
M = 20/24 = 5/6 Kg
now, when two masses combine together
F = (M1 + M) a'
20 = (20 + 5/6) × a'
20 = (125)/6 × a'
4 = 25/6 × a'
a' = 24/25 m/s²
