The figure presents the graph of velocity versus time for a particle going along the X-axis. Determine the acceleration in m/s ^2 .

Options

A0.8
B0.6
C1.0
D0.2

Correct answer

B. 0.6

Step-by-step solution

From the given velocity-time graph, the velocity at t = 0 is u = 2 m/s . The velocity at t = 10 s is v = 8 m/s . The acceleration of the particle is equal to the slope of the v-t graph: a = v t = 8 - 2 10 - 0 a = 6 10 = 0.6 m/s ^2
