An iceboat sails across the surface of a frozen lake with con- stant acceleration produced by the wind. At a certain instant its velocity is in m/s. Three seconds later the boat is instantaneously at rest. What is its acceleration during this interval?

Therefore, the magnitude of acceleration experienced by the boat is -3.5 m/s2.
The acceleration vector of the boat is:
