A force of 5 N gives a mass m1 and acceleration of 10m/s and a mass m2 an acceleration of 20m/s . What acceleration would it give if both the masses are tied together ?

➡➡➡➡➡➡➡➡➡➡➡➡➡

Given :-
F = 5 N

a1 = 10 m/s

a2 = 20 m/s


M1 = \frac{F}{a1}


=》\frac{5}{10}


=》 0.5 kg

M2 = \frac{F}{a2}


=》 \frac{5}{20}


=》 0.25 kg

⚫When two masses are TIED TOGETHER, the total mass becomes.

m = m1 + m2

m = 0.5 + 0.25

m = 0.75 kg

The ACCELERATION produced in the combined mass by the force of 5 N is

a = \frac{F}{m}


=》 \frac{5}{0.75}


=》6.67 m/s \boxed{Ans}
