Question

a trolley while going down an inclined plane has an acceleration of 2 centimetre square what will be the velocity 3 seconds after the start

Answer 1

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

Answer 2

➧ a ➾ 2 cm/s²
➧ u ➾ 0
➧ t ➾ 3 sec
➧ v ➾ ?

❱ So, v = u + at

v = 0 + (2 cm/s²) × (3 s)
v = 0 + 6 cm/s
v = 6 cm/s ...✔
