......???????????.....?!!! Viiiiiix

Answer 1

$1)f = m.a \\ f = 0.5 \times 0.2 \\ f = 0.1 \\ \\ 2)f = m.a \\ 200 = m \times 2.5 \\ m = \frac{200}{2.5} \\ m = 80 \\ \\ 3)f = m.a \\ 8 = 20 \times a \\ a = \frac{8}{20} \\ a = 0.4 \\ 4)f = m.a \\ 25 = 1.25 \times a \\ a = \frac{25}{1.25} \\ a = 20 \\ 5)f = m.a \\ f = 6 \times 0.5 \\ f = 3$
