Two boats are separated by a distance of 60 meters. The boats start a rest and accelerate towards each other at a constant rate of 0.7 m/s2. A dolphin starts mid-way between the two boats, swimming from one boat to the other at a constant speed of 16 m/s. The dolphin continues swimming back and forth between the boats until the boats crash together. What is the total distance the dolphin travelled? what is the speed of the boats when...

An ice sled powered by a rocket engine starts from rest on a large frozen lake and accelerates at +39 ft/s2. After some time t1, the rocket engine is shut down and the sled moves with constant velocity v for a time t2. If the total distance traveled by the sled is 18,250 ft and the total time is 90 s, find the following. (a) the times t1 and t2 t1 = ___ s t2 = ____ s (b) the...

A simple harmonic oscillator is made from a mass on a spring. If you start the mass oscillating by pulling the mass downward by a distance A and releasing it from rest, let us assume the maximum velocity it achieves during its oscillation is v. What would the maximum velocity be if you instead pulled the mass down by 2A then released it from rest?
