Newton's second law of motion states that a net force acts on a body gives it an
acceleration which is in the direction of the net force and has a magnitude
given by mass x acceleration (m x a). Newton's 2nd law formula is $$\sum { \vec
{ F } } =m\vec { a } $$ Here a⃗ stands for acceleration, m for the mass, and
∑F⃗ for the net force on the object which is vector sum of the forces acting on
it. Vector equation can be written in component form in rectangular coordinates as
$$\sum { { F }_{ x } } =m{ a }_{ x }\quad ,\quad \sum { { F }_{ y } } =m{ a }_{
y }\quad ,\quad \sum { { F }_{ z } } =m{ a }_{ z }$$
Note: Use dot "." as decimal separator.

Note: Default rounding is 7 decimal places.
Calculate the net force needed to accelerate (a) a 1200kg car at 1/4 g. Calculate the density of the object?
$$\sum { { F } } =\quad m{ a }\quad =\quad (1200kg)\quad
(2.45m/{ s }^{ 2 })\quad =\quad 2940\quad N\quad \quad $$
