An object undergoes an accelerations of\[\text{8m}/{{\text{s}}^{\text{2}}}\]starting from rest. Find the distance travelled in one second.

Answer:

Here, \[u=0,\,\,a=8m/{{s}^{2}},\,\,t=1s,\] s = ? (to be calculate(d) From formula, \[s=ut+\frac{1}{2}a{{t}^{2}}\] Putting values, we get, \[s=0\times 1+\frac{1}{2}\times 8\times {{(1)}^{2}}\] or s = 4m.
