Question

How much force is needed to accelerate a 900-kg car at a rate of 3 m/s2

Answer 1

Force=mass×acceleration

=900kg×3m/s2

=2700kg×m/s2

Force=2700Newtons.

Answer 2

force = 2.7 killo Newton

Given :-

$\sf{mass \: of \: the \: car \: (m) = 900 \: kg}$

$\sf{acceleration \: (a) = 3 \: m/s^{2}}$

To Find :-

$\sf{How \: much \: force \: is \: needed \: to \: accelerate \: that \: car \: ?}$

Using Formula :-

By Second law of Newton's motion -

$\sf{applied \: Force = mass\times acceleration}$

Explanation :-

$\sf{From \: Formula -}$

$\sf{F = ma}$

putting the values of force & acceleration -

$\sf{F = 900\times 3}$

$\sf{F = 2700 \: Newton}$

$\sf{F = 2.7 \: killo \: Newton}$
