Question

a ship moves at a speed of 56 km/h one second later is moving at 58 km/h what is the acceleration in m/s^2​

Answer 1

Answer: first convert it into metre per second

56000/3600 and 58000/3600 m/s

T= 1 sec.

Acceleration

=V-U/t

58000/3600-56000/3600/1

2000/3600

20/36=0.555m/s

Or approximately 0.56m/s

Answer 2

Answer:

Explanation:

Solution,

Here, we have

The initial speed of the ship, u = 56 km/h

Final speed of the ship, v = 58 km/h

Time taken by ship, t = 1/60 × 60 h

To Calculate,

Acceleration of ship, a = ??

According to the 1st equation of motion,

we know that,

v = u + at

So, putting alll the values, we get

v = u + at

⇒ a = v - u/t

⇒ a = 58 - 56/1/60 × 60

⇒ a = 7200 km/h²

In metres/second

⇒ a = 0.56 m/s²

Hence, the acceleration of ship is 7200 km/h² in km/h and 0.56 m/s² in m/s.
