A ship has engines capable of an acceleration of-0.357m/s2 to stop. If the ship approaches the dock at a speed of 16.98m/s, how much time does the ship meed to stop

time is 47.56sec

Explanation: acceleration is define as the rate of change of velocity. That is,

Acceleration = velocity/time

Since we're told to find the time we can make time t the subject of formula in the above equation.

So we have,

Time = Velocity/Acceleration

But from the question velocity is given as 16.98 m/s while acceleration is given as 0.357m/s²

So we have,

Time = 16.98/0.357 = 47.56seconds
