A particle starts from rest and moves in a straight line with alternate acceleration $4 m / s^{2}$ and retardation $2 m / s^{2}$ , each applied for 1 s at a time. The distance described at the end of 10 such intervals is:

Answer:

Solution:

$S = t^{2} [n^{2} (a - a^{'}) + \frac{n ( a + a ^{'} )}{2}] = 1 \times [25 \times 2 + 5 \times 3] = 65 m$ .
