Vedclass · Answer

(D) The formula for distance traveled in the $n^{th}$ second is given by $S_n = u + \frac{a}{2}(2n - 1)$.Given that the body starts from rest,the initial velocity $u = 0 \, m/s$.The distance traveled in the $6^{th}$ second is $S_6 = 120 \, cm = 1.2 \, m$.Substituting the values into the formula:$1.2 = 0 + \frac{a}{2}(2 	imes 6 - 1)$$1.2 = \frac{a}{2}(11)$$a = \frac{1.2 	imes 2}{11} = \frac{2.4}{11} \, m/s^2 \approx 0.218 \, m/s^2$.Converting back to $cm/s^2$:$a = 0.218 	imes 100 \, cm/s^2 = 21.8 \, cm/s^2$.

If a body starts from rest and travels $120 \, cm$ in the $6^{th}$ second,then the acceleration of the body is:

$A$ particle starts from the origin at time $t=0$ and moves in the positive $x$-direction. Its velocity $v$ varies with time as $v=10t \text{ cm/s}$. The distance covered by the particle in $8 \text{ s}$ will be: (in $\text{ cm}$)

What kind of motion is represented by the equation $\Delta S = v \Delta t$?

$A$ moving body is covering distances which are proportional to the square of the time. Then the acceleration of the body is

$A$ particle experiences a constant acceleration for $20\, s$ after starting from rest. If it travels a distance $s_1$ in the first $10\, s$ and a distance $s_2$ in the next $10\, s$,then:
