A boat accelerates from 0 m/s (rest) to reach a speed of 45.0 km/h over
a distance of 90.0 m and then continues with the same constant acceleration for another 15.0 s before slowing down to 30.0 km/h over a distance of 150. m. Another boat begins to accelerate from 0 m/s (rest) at the same spot as the first boat and catches up to the first boat within 45.0 s.
(a) What is the acceleration of the second boat.
(b) What is the time it takes the first boat to cover the first 90 m.
(c) What is the speed of the second boat when it catches up to the first boat
Given that:
Speed = 45 km/h
Distance = 150 m
Time = 45.0 s
