Question

Motion described by an object is shown in the figure given below, the acceleration of the object is

• A. $5{\text{m/s}}^2$
• B. $20{\text{m/s}}^2$
• C. $10{\text{m/s}}^2$
• D. $15{\text{m/s}}^2$

Answer 1

The correct option is C $10{\text{m/s}}^2$

Given, the motion of an object as
We know that the acceleration of the object is the slope of $v-t$ curve
Therefore, $a=\frac{\Delta v}{\Delta t}=\frac{20-0}{2-0}=10{\text{m/s}}^2$
