Question

m1 and m2 are the masses of two bodies when force pf 5N is applied on each body ,m1 gets an acceleration of 10m/square and m2 20m/square .If two bodies are tried together and the same force is applied .find the acceleration of the combined system​

Answer 1

Answer:

$= 6.66m/s^{2}$

Explanation:

F = 5N

a  1   = $= 10m/s^{2}$

 F=m 1   a  1

​ m  1  =  $\frac{F}{a1}$

F = m1a1

m1 = $\frac{F}{a1}$

$= \frac{5}{10} = 0.5kg$

F = 5N

a2 = $20m/s^{2}$

F = m2a2 ​  

$= \frac{5}{20} = 0.25kg$

m1 + m2 = 0.5 + 0.25

= 0.75 kg

F=5N

F = ma

​a = $\frac{F}{m}$

$= \frac{5}{0.75}$  

= $6.66m/s^{2}$

Hope this answer helped you out , ,have a nice day
