Question

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

Answer 1

Step-by-step explanation:

F=ma

m1=F/a1

and m2=F/a2

here a1= 10m/s² &a2=20m/s²

force=5N

m1=5/10=0.5kg

m2=5/20= 0.4 kg

now , m1+m2= 0.9kg

and F=5N(given)

thus,

a= F/M

a= 5/0.9

a=5.55m/s²

NOTE : F=force

a1= acceleration of 10m/s²

a2= acceleration of 20m/s²

a= final acceleration

M= total mass i.e, m1+m2

m1 = mass of 1st object

m2= mass of 2nd object
