Two boats start together and race across a 72 km wide lake and back. Boat A goes across at 72 km/h and returns at 72 km/h. Boat B goes across at 36 km/h, and its crew, realizing how far behind it is getting, returns at 108 km/h. Turnaround times are negligible, and the boat that completes the round-trip first wins.

Two boats start together and race across a 42-km-wide lake and back. Boat A goes across at 42 km/h and returns at 42 km/h. Boat B goes across at 21 km/h, and its crew, realizing how far behind it is getting, returns at 63 km/h. Turnaround times are negligible, and the boat that completes the round trip first wins.Which boat wins? (Or is it a tie?) By how much? What is the average velocity of the winning boat?
A red train traveling at 20 m/s and a green train traveling at 40 m/s are headed toward one another along a straight, level track. When they are 950 m apart, each engineer sees the other's train and applies the breaks. The breaks decelerates each train at the rate of 1 m/s˄2. What is the speed (in m/s) of the green train at impact?
A spy in a speed boat is being chased down a river by government officials in a faster craft. Just as the officials' boat pulls up next to the spy's boat, both reach the edge of a 7.3 m waterfall. If the spy's speed is 11 m/s and the officials' speed is 27 m/s, how far apart will the two vessels be when they land below the waterfall?

A classic wooden coaster has cars that go down a big first hill, gaining speed. The cars then ascend a second hill with a slope of 30°. If the cars are going 25 m/s at the bottom and it takes them 2.0 s to climb this hill, how fast are they going at the top?
A boy leaning over a railway bridge 49 ft high sees a train approaching with uniform speed attempts to drop a ball down the tunnel. He releases the ball when the engine is 80 ft away from the bridge and sees the ball hit the ground 3 ft in front of the engine. What is the speed of the train ( in ft/sec)?
Two boats start together and race across a 52-km-wide lake and back. Boat A goes across at 52 km/h and returns at 52 km/h. Boat B goes across at 26 km/h, and its crew, realizing how far behind it is getting, returns at 78 km/h. Turnaround times are negligible, and the boat that completes the round trip first wins. (a) Which boat wins? (Or is it a tie?) boat Aboat B It's a tie. By how much? Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. km (b) What is the average velocity of the winning boat? km/h
A man and his dog are out for a run at 12 km/hr, traveling toward a road 100 km away. At the 30 km mark, he decides to unleash the dog, and it runs back and forth between its owner and the road at 35 km/hr (fast dog) while he continues at his same pace. What is the total distance the dog has run by the time the man reaches the road? 234 km 200 km 300 km 156 km

two friend 50m apart are walking towards each other in a straight road. Man A is walking at a speed of 0.25m/s while the Man B is walking at 0.8m/s. If a pigeon above man A flies towards man B at a constant speed of 5 m/s and flies back again to man A when it is above man B. This goes on until two friends meet. Assuming that there is no speed loss every time the pigeon changes its direction. Determine the total distance that the pigeon flew?
Two trains, each having a speed of 30 km/h, are headed at each other on the same straight track. A bird that can fly 60 km/h flies off the front of one train when they are 60 km apart and heads directly for the other train. On reaching the other train, the (crazy) bird flies directly back to the first train, and so forth.What is the total distance the bird travels before the trains collide?
