Question

The V - t graph is shown in the figure for particle the (V m/s) acceleration of particle is

• A. $22.5m/s^2$
• B. $5m/s^2$
• C. $-5m/s^2$
• D. $-3m/s^2$

Answer 1

Answer: (B)

$5m/s^2$

Let u is the initial velocity and v is the final velocity. Acceleration produced is given by

$a=\frac{v-u}{t}$

From the graph,

$u=0$

$v=15m/s$

$a=\frac{15}{3}=5m/s^2$
