Question

a ship is moving at a speed of 56 km per hour 1 second later it is moving at 58 km per hour what is its acceleration

Answer 1

Answer: 7200 km/ hr²

Explanation:

The speed changes from 56 km/hr to 58km/hr therefore,

Initial speed (u) = 56 km/hr

Final speed (v) = 58 km/hr

Time (t) = 1 sec = 1/3600 hour

Using the first kinematic equation i.e.,

v = u + at

We get : 58 = 56 + a (1/3600)

a = 7200 km/hr²
