A) 5 sec.
B) 10 sec.
C) 15 sec.
D) 30 sec.
Correct Answer: D
Solution :
[d] For \[{{t}_{\min }}\] motion of particle is shown in \[v-t\] graph is | |
For accelerating motion \[\frac{{{v}_{0}}}{{{t}_{0}}}=5\] | ...(i) |
For retarding motion \[\frac{{{v}_{0}}}{T-{{t}_{0}}}=10\] | ...(ii) |
Distance = area of \[v-t\] curve | |
\[\frac{1}{2}{{v}_{0}}T=1500\] | ...(iii) |
From equation (i), (ii) & (iii) \[T=30\sec \] Ans. |
