Question

Plz plz help
its urgent ​

Answer 1

Force = mass × acceleration

5 = m1 × 10

m1 = 5/10 = 0.5 kg

........ I think you skipped a line in the question which makes it not possible to solve any further..

Answer 2

Step-by-step explanation:

F = m1 *a

5=m1*10

therefore m1= 1/2

F=m2*a

5=m2*20

therefore m2= 1/4

m1 +m2 = 1/2+1/4

m =3/4

therefore

F= m*a

5=3/4 *a

a= 5*4/3

therefore a= 6.67 m/s^2
