Question

A tugboat decelerates to 0.0031 km/s2 as it approaches the port. What is its deceleration in knot per second (kn/s)? Note: 1 knot = 1 nm/h, 1 nm = 1.852 km, 1 h = 3,600 s.

Answer 1

Explanation:

1 Knot per second is equal to an acceleration of one nautical mile an hour per second. 1 Knot per second is approximately 0.514444444 meters per second squared (SI unit). 1 kn/s = 0.514444444 m/s2.
