Question

If force of 9.8 Newtons work on 1.0 kg of a body. then how much distance it will cover in 4 seconds??

Answer 1

we know that F=MA,
therefore 9.8=1*A,
so, A=9.8m/s

Apply,
2nd equation of motion
$s = ut + \frac{1}{2} {at}^{2}$
$s = 0 + \frac{1}{2} \times 9.8 \times {4}^{2}$
$s = 78.4$
hence distance covered is 78.4 meters.
