Find change in velocity when Acceleration of 10m/square second and time is 2 min
Answers
Change in Velocity = t × a
= 10 × 2
= 20

Answer:
We can answer it in two ways……
1st…..
As initial velocity is not given…so assume it to be zero i.e. rest position
And a=10 m/s^2 ( acceleration =change in velocity w.r.t time)
That means …..after each second velocity will increase by 10.
At time… t=0……v=0
At t=1 second….v=10m/s ( increased by 10)
At t=2second……v= 20 m/s( again increased by 10)
At t=3 second ….. v=30m/s (again incresesd by 10)
And this is our required velocity i.e.after 3 second.
2nd …
Just use the 1st equation of motion ,
v=u +at
As u =0 ( intial velocity ) , a= 10m/s^2 , t= 3sec.
Putting all the values…
v= 0 +10×3
v= 30 m/s.
