Question

A ship is moving at a speed of 56 km/h. One second later, it is moving at 58 km/h. What is
its acceleration ?​

Answer 1

Answer:

2 km/hr or 5/9 m/s

Explanation:

Given,

final velocity (v) = 58 km/hr = 145/9 m/s

initial velocity(u) = 56 km/hr = 140/9 m/s

Time taken(t) = 1 sec

Therefore,

acceleration(a) = (v-u)/t

=⟩ a = (145/9 - 140/9)/1

=⟩ a = 5/9 m/s = 2 km/hr
