Question

A ship is moving at a speed of 56 km/h. On second later, is found to be moving at 58 km/h , what is the acceleration of the ship?
[Ans. 0.56 ms² or 7, 200 Kmh^2]​

Answer 1

$\tt\huge{\red{AnsweR:-}}$

$\tt\large{\pink{GiveN:-}}$

♦️Speed:- 56km/h(ship moving)

♦️Speed:- 58km/h(second later found)

$\tt\large{\pink{To\: find:-}}$

♣️Acceleration:-?

$\tt\Large{\red{SolutioN:-}}$

$\tt\large{\green{By\:using\: formula:-}}$

Acceleration= change in velocity/change in time

=>a={(58–56)km/hr}/1 second

=>a={2km/hr}/1 second

=>a={2×(1000/3600)m/s}/1 second

=>a=0.56m/s^²
