Question

A particle starts from rest. Its acceleration (a) versus time (t) is as shown in the figure. The maximum speed of the particle will be (A) 110 m/s (B) 55 m/s (C) 550 m/s (D) 660 m/s

Area under acceleration-time graph gives the change in velocity. Hence, vmax=1/2 × 10 × 11=55 m/s Therefore, the correct option is (b).

is as shown in the figure. The maximum speed of the particle
will be

110 m/s

55 m/s

550 m/s

660 m/s

Area under acceleration-time graph gives the change in velocity.
Hence, $v_{ma x} = 1/2 \times 10 \times 11 = 55 m / s$
Therefore, the correct option is (b).
