A trolley while going down an inclined plain,has an acceleration of 2m/s2.What will be its velocity 3 seconds after the start?

answered-by-expert Expert Answer
Here, acceleration, a = 2 m/s2
 
        time taken, t = 3 s
 
        initial velocity, u = 0
 
        final velocity, v = ?
 
 
We know, v = u + at
 
               v = 0 + 2 x 3
 
         =>  v = 6 m/s
