A roadrunner is cruising at 14 m/s without knowing the road under its feet is about to run out, at the edge of a cliff, some 45 m above a flat valley below. Fortunately a roadrunner CAN fly so it just flew away. If indeed the roadrunner couldn't fly and would not be affected by air drag, what was the magnitude of the final speed when it hit the valley?

- A sailor is stuck on a tropical island and emergency supplies are airlifted to her before the ship can come to her rescue. The supply plane is flying at an altitude of H = 200 ft and it is moving horizontally at a speed of 250 mph. How far before the island must the supply package be released if it is to just reach the island?A criminal in a speed boat is being chased down a river by the police in a faster boat. Just as the police boat pulls up next to the criminal’s boat, both boats reach the edge of a 7 m waterfall. If the criminal’s boat speed is 10 m/s and the police’s speed is 18 m/s, how far apart will the two vessels be when they land below the waterfall?A daredevil decides to jump a canyon of width 10 m. To do so, he drives a motorcycle up an incline sloped at an angle of 15°. What minimum speed must he have in order to clear the canyon?
- A ball is thrown horizontally from a height of 20 m and hits the ground with a speed that is three times its initial speed. What is its initial speed?Imagine that you hit a ball at ground level and send it toward the wall with a speed at 18 m/s at an angle of 32° above the horizontal. (a) How long does it take for the ball to reach the wall if it is 3.8 m away. (b) How high is the ball when it hits the wall?1. A physics book slides off a horizontal table top with a speed of 1.10 m/s. It strikes the floor in 0.350 s. Ignore air resistance. Find (a) the height of the table top above the floor; (b) the horizontal distance from the edge of the table to the point where the book strikes the floor; (c) the horizontal and vertical components of the book’s velocity, and the magnitude and direction of its velocity, just before the book reaches the floor. (d) Draw x-t, y-t, and graphs for the motion.
- A golf ball rolls off a horizontal cliff with an initial speed of 10.5 m/s. The ball falls a vertical distance of 14.1 m into a lake below. (a) How much time does the ball spend in the air? (b) What is the speed v of the ball just before it strikes the water? (a) Number (b) Number i i Units Units ♦A ball is dropped (from rest) from a window and hits the ground with a speed of 7.0m/s. If the ball were dropped from double the height, what would be its speed (in m/s) when it hits the ground? Your Answer:Two snow-covered peaks are at elevations of 862 m and 741 m above the valley between them. If a skier starts from rest on the higher peak and just coasted down without exerting any effort, at what speed would he arrive at the lower peak?
- !, Suppose that a young Peter Parker wanted to clear a cubic building that is 30 x 30 x 30 m when he is exactly 30 m away from the closer side. What is the minimum speed that he must jump at (if he can launch at a 60 degree angle above the horizontal) in order to just barely clear the building?Standing on the roof of a 95-m tall building, a girl holds her hand past the edge and throws a ball straight up at 8 m/s. The ball rises, then falls and strikes the ground. Considering "up" to be the positive direction, find the ball's velocity v when it is 40 m above the ground. Remember to include a "-" sign if the velocity is negative. V = m/sThe Hulk, on the 75th story of Stark Tower (225 m off the ground), sees Tony drop his penny. He catches the penny and throws it back to Tony. What is the minimum speed necessary for Hulk's throw in order for the penny to reach Tony? (Note: nobody bothers trying to get Mjolnir back to Thor. He's on his own.)
