The velocity of particle at any instant is 10 metre per second after 5 second the velocity of particle is 20 metre per second the velocity at 3 second before his |

Answer» We first get the ACCELERATION of the particle. Acceleration = change in speed / change in time This equals to : 20 - 10 = 10 10 / 2 = 5m/s² The speed after 3 SECONDS is : (V - 10) / 3 = 5 V - 10 = 15 V = 25 m / s |
