Finn · Answer 1

F = 20N m = m1 a=10m/s²

m=m2 a=5m/s²

F = ma

for the first one:

f=m1 * a

20 = m1 * 10

20=10m1

m1=20/10

m1=2

for the second one:

f=m2*a

20=m2*5

m2 = 20/5

m2 = 4

since F=ma

F = (m1+m2) * a

F = (4+2) * a

F = 6*a

F=20 (from the question above)

20=6*a

a=20/6

a=3.33

Hebert · Answer 2

force : 20N

acceleration : 10m/s^2

mass 1 : m1

acceleration : 5m/s^2

mass 2 : m2

f = ma

20 = m1 * 10

m1 = 2

20 = m2 * 5

m2 = 4

m1 + m2 = 2 + 4

= 6

f = ma

20 = 6 * a

a = 3.3
