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
$=\text{a}=\frac{(\text{v}-\text{u})}{\text{t}}$
$=\frac{(0-5)}{40}$
$=-\frac{50}{40}$
$=-\frac{5}{4}=1.25\text{m/s}^{2}$
initial velocity $= u = 50m/s$
final velocity $= v = 0m/s$ so acceleration
$=\text{a}=\frac{(\text{v}-\text{u})}{\text{t}}$
$=\frac{(0-5)}{40}$
$=-\frac{50}{40}$
$=-\frac{5}{4}=1.25\text{m/s}^{2}$

The scientists now say that there are actually five states of matter $A, B, C, D$ and $E$. The state A has a fixed volume but no fixed shape. The state B can be compressed very easily by applying pressure and state $C$ has a fixed shape as well as a fixed volume. The state $D$ is mixture of free electrons and ions whereas state E is named after an Indian scientist and a famous physicist.
