Question

Given below is the velocity-time graph for the motion of the car. What does the nature of the graph show ? Also find the acceleration of the car.

​

Answer 1

Answer:

The nature of the graph shows that car has a uniform acceleration

Acceleration = (v-u)/t

v = 10 m/s

u = 0 m/s

time taken = 20 sec

= (10-0)/20

= 10 / 20

= 1/2 m/s²

or

0.5 m/s²

Answer 2

The nature of graph show that the car has uniform acceleration and acceleration of car is 0.5m/sec^2

explanation=

u or initial velocity = 0 m/sec

v or final velocity = 10 m/sec

time or t = 20

acceleration or a = ?

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

$a = \frac{10 - 0}{20}$

$a = \frac{10}{20}$

$a = \frac{1}{2}$

$a = 0.5 {m/sec}^{2}$
