Question

a particle moving with uniform acceleration has an initial velocity 10m/s and after 15 minutes, it's velocity become 40m/s. what is its acceleration. ​

Answer 1

Given,

u=10m/s

a=2m/s  

2

 

t=4sec

Acceleration, a=  

t

v−u

​  

 

2=  

4

v−10

​  

 

v=10+8=18m/s  

The correct option is D.

Answer 2

Answer:

14:10
