Question

A vehicle starts from rest. After
y second its velocity reached 12 mls then
find the acceleration of that vehicle.​

Answer 1

Answer: Explanation:

Given that,

Time t=10sec

Velocity v=12km/h=  

18

12×5

​  

m/s

Now, the acceleration is

Using of equation of motion

v=u+at

12×  

18

5

​  

=0+a×10

a=  

10×18

12×5

​  

 

a=  

3

1

​  

m/s  

2

 

Hence, the acceleration is  

3

1

​  

m/s
