(a) Derive the formula : v = u + at, where the symbols have usual meanings. |

Answer» Consider a body of mass “m” having initial velocity “U”.Let after time “t” its FINAL velocity becomes “v” due to uniform acceleration “a”. Now we know that: Acceleration = CHANGE in velocity/Time taken => Acceleration = Final velocity-Initial velocity / time taken => a = v-u /t =>at = v-u or v = u + at This is the first equation of motion. |
