Question

27. A force of 5N gives a mass m;, an acceleration of 20 m/s" and a mass m2, an acceleration of
5 m/s. What acceleration would it give if both the masses were tied together?​

Answer 1

Answer:

Answer

For mass m1

newton 2nd law

F=m1a1

5=m1×10

m1=21kg

For mass m2

F=m2a2

5=m2×20

m2=41kg

if tied together 

Total mass =m1+m2=21+41=43kg

Now

F=MTQT

aT=mT5=35×4=320m/s2
