Kinematics 4 Question 7

7. 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

(2004, 2M)

(a) 110m/s

(b) 55m/s

(c) 550m/s

(d) 660m/s

Show Answer

Solution:

  1. Area under acceleration-time graph gives the change in velocity.

Hence, vmax=1/2×10×11=55m/s
