How long does it take to accelerate an object from rest to 15 m/s if the acceleration is 3 m/s^2? |
|
Answer» u = 0 m/sv = 15 m/sa = 3 m/s²To FIND :-The total time takenSolution :-From the first EQUATION of motion we have,v = u + at=> 15 = 0 + 3 × t=> 15 = 3t=> t = 5 Therefore, total time taken was 5 secondsShort-hands :-u = Initial velocityv = Final velocitya = accelerationt = time |
