Question

If m1= 5 kg and m2 = 5 kg, wat would be a? (g = 10 m/s/s)

A.5m/s/s

B.10m/s/s

C.8m/s/s

D.6m/s/s

Answer 1

a = 3.9m/s ²

Step-by-step explanation:

The diagram is as shown

From the diagram, we can set up a simultaneous equation as shown;

T - F = m1a

W - T = m2a

Add both equation

-F + W = (m1 + m2)a

F is the frictional force

W is the weight

a is the acceleration

Let F = 10N since we are not given'

-10 + 5(9.8) = (5+5)a

-10 + 49 = 10a

39 = 10a

a = 39/10

a = 3.9m/s ²

Note that the frictional force was assumed
