Answer 1

$\huge{\underline{\mathfrak{\red{R}\pink{e}\green{q}\blue{u}\purple{i}\orange{r}\purple{e}\pink{d-}\red{A}\blue{n}\pink{s}\green{w}\purple{e}\orange{r}}}}$

$v = u + t \\ a = \frac{v - u}{t} \\ f = ma = \frac{m(v - u)}{t} \\ = \frac{1000(0 - \frac{40 \times 1000)}{3600} }{5 } \\ = \frac{ - 2000}{9} \\ = - 2222.22n$
