Question

. A ship is moving at a speed of 56 km/h. One second later, it is found to be moving at 58 km/h, what
is the acceleration of the ship?
[Ans. 0.56 ms 2 or 7,200 kmh ?)
​

Answer 1

Answer:

2 is the right answer

Explanation:v-u/t =58-56/1

=2m/s^2

Answer 2

Answer:

: 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=(v-u)/t

a=(16.11-15.55)/1

a=0.56ms^2 or 7,200 kmh..

,,,hope u like my explanation...✓
