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

\text{m/s}^2

.

The figure presents the graph of velocity versus time for a particle going along the X-axis. Determine the acceleration

Options

A $0.8$
B $0.6$
C $1.0$
D $0.2$

Correct answer

B. $0.6$

Step-by-step solution

From the given velocity-time graph, the velocity at

t = 0

is

u = 2 \text{ m/s}

.

The velocity at

t = 10 \text{ s}

is

v = 8 \text{ m/s}

.

The acceleration of the particle is equal to the slope of the

v-t

graph:

a = \dfrac{\Delta v}{\Delta t} = \dfrac{8 - 2}{10 - 0}

a = \dfrac{6}{10} = 0.6 \text{ m/s}^2
