a ball rolls down a ramp for 5 second.if the initial velocity of the ball was 10 m/sec and the final velocity is 30m/sec,what was the acceleration of the ball? with solution |

Answer» 4 m/s²Step-by-step EXPLANATION:initial velocity, U = 10 m/sfinal velocity, v = 30 m/stime, t = 5 secNow,Acceleration = FINAL velocity - initial velocity / TIME = 30 - 10 m/s / 5 = 20 / 5 = 4 m/s² |
