IB Physics SL A 1 6 Uniform Acceleration Equations Topic Practice

This question is in two parts. Part 1 is about the motion of a ship. Part 2 is about melting ice.

The ship's engines are switched off and the ship comes to rest from a speed of $7 \mathrm{~m} \mathrm{~s}^{-1}$ in a time of 650 s .

Estimate the distance that the ship takes to stop. Assume that the acceleration is uniform.
