A motorboat traveling on a straight coures slows uniformlyfrom 60 to 40 km/h in a distance of 50m. What is the boatsacceleration?
Texk book answer is Initial velocity for 60km/h = 16.68ms andFinal velocity is 40km/h = 11.12m/s
I'm guessing avg boats acceleration? 16.68 + 11.12 / 2 =13.9 m/s
Is this correct?
