A ship is moving at a speed of 56 km per hour.One second later it it is moving at 58 km/h what is it is acceleration |
|
Answer» Answer: Method I: Initial speed=u=56km/h=56 X 5/18=15.55m/s Final speed=v=58km/h=58x5/18=16.11m/s Time=t=1sec ACCELERATION=a=? as we know that acceleration is RATE of CHANGE of velocity. a=(v-u)/t =(16.11-15.55)/1 =0.56 m/s² Method 2: Initial speed=u=56km/h Final speed=v=58km/h Time=t=1/60x60 h acceleration=a=? as we know that acceleration is rate of change of velocity. a=(v-u)/t =(58-56)/1/60*60 =2x3600 =7200 Km/h² ∴ Acceleration is 0.56 m/s² or 7200 Km/h² Read more on Brainly.in - brainly.in/question/22525#readmore |
