A particle starts from rest. Its acceleration a versus time t is shown in the figure. The maximum speed of the particle will be

Options

  1. A80 ~ms ⁻¹
  2. B40 ~ms ⁻¹
  3. C18 ~ms ⁻¹
  4. D2 ~ms ⁻¹

Correct answer

B. 40 ~ms ⁻¹

Step-by-step solution

As, we know Area under a-t graph =v-u array ll & 1 2 8 10=v ( u=0) & v=40 ~ms ⁻¹ array
