→ Answer :

Velocity of an object in next five seconds is 40 m/s

→ Step-by-step explanation :

Given ,

Initial Velocity (u) = 10 m/s

Final Velocity (v) = 25 m/s

Time (t) = 5 seconds

=> Acceleration = (Change in velocity)/Time

=> a = ( v - u ) / t

=> a = ( 25 - 10 ) / 5

=> a = 3 m/s^2

So ,  velocity of an object in next five seconds is ,

v = u + at

Here u = 25 m/s , a = 3 m/s^2 , t = 5 seconds

=> v = 25 + 3 * 5

=> v = 25 + 15

=> v = 40 m/s
