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 they crash together?

1. Two objects (A and B) are at rest and separated by a distance of 1200 meters. At the same moment, they accelerate towards each other. The magnitude of the acceleration of A is 6 m / s2, while the magnitude of the acceleration of B is 2 m / s2. Eventually the objects collide, as illustrated.

Fred and Sara meet at a lake to race their boats. The boats start at one end of the lake and travel 126 m straight across the lake and then return to where they started. Fred's boat goes across with an average speed 57.5 km/h and returns with that same average speed of 57.5 km/h. Sara's boat travels with an average speed of 31.1 km/h across the lake and then travels with an average speed of 88.8 km/h on the...

Two cars start from rest at a red stop light. When the light turns green, both cars accelerate forward. The blue car accelerates uniformly at a rate of 5.7 m/s2 for 3.1 seconds. It then continues at a constant speed for 8.4 seconds, before applying the brakes such that the car’s speed decreases uniformly coming to rest 202 meters from where it started. The yellow car accelerates uniformly for the entire distance, finally catching the blue car just as the...

A tortoise and hare start from rest and have a race. As the race begins, both accelerate forward. The hare accelerates uniformly at a rate of 1.5 m/s2 for 4.2 seconds. It then continues at a constant speed for 12.4 seconds, before getting tired and slowing down with constant acceleration coming to rest 108 meters from where it started. The tortoise accelerates uniformly for the entire distance, finally catching the hare just as the hare comes to a stop. 1)...
