A ship travels 2200 m, east in 425 s. If the ship's initial velocity is
5.7 m/s, east, what is the ship's acceleration?

Respuesta :

The acceleration of the ship is –0.0012 m/s²

What is acceleration?

This is defined as the rate of change of velocity which time. It is expressed as

a = (v – u) / t

Where

  • a is the acceleration
  • v is the final velocity
  • u is the initial velocity
  • t is the time

How to de terminate final velocity

  • Displacement = 2200 m east
  • Time = 425 s
  • Velocity = ?

Velocity = displacement / time

Velocity = 2200 / 425

Velocity = 5.2 m/s

How to determine the acceleration of the ship

The acceleration of the ship can be obtained as follow:

  • Initial velocity (u) = 5.7 m/s
  • Final velocity (v) = 5.2 m/s
  • Time (t) = 425 s
  • Acceleration (a) =?

a = (v – u) / t

a = (5.2 – 5.7) / 425

a = –0.5 / 425

a = –0.0012 m/s²
