Question
What is the value of acceleration in the following graph:
✓
Answer
According to the graph the object is in a non-uniform motion as it is continuously retarding. In this graph time = 40sec initial velocity = u = 50m/s final velocity = v = 0m/s so acceleration $=\text{a}=\frac{(\text{v}-\text{u})}{\text{t}}$
$=\frac{(0-5)}{40}$
$=-\frac{50}{40}$
$=-\frac{5}{4}=1.25\text{m/s}^{2}$
