Question

a car starts moving along a line first with acceleration a=2m/s startng from rest and then

Answer 1

then ?? what u want to know ??

Answer 2

So , here is the answer
$a = 2 \frac{m}{ {s}^{2} } \\ u = 0 \\ total \: time \: = 10sec \\ av.sp = 3.2 \frac{m}{s} \\ \\ av.sp = \frac{total \: distance}{total \:time } \\ \frac{32}{10} = \frac{s}{10} \\ s = 32m \\ \\ s = ut + \frac{1}{2}a {t}^{2} \\ 32 = 0 + \frac{1}{2} \times 2 \times {t}^{2} \\ 32 = {t}^{2} \\ t = \sqrt{32} \\ t = 4 \sqrt{2} \\ t = 4 \times 1.414 \\ t = 5.64 \\ t = 6sec$
