In an experiment, a shearwater (a seabird) was taken from its nest, flown a distance 5040 km away, and released. It found its way back to its nest a time 12.4 days after release. If we place the origin in the nest and extend the +x-axis to the release point, what was the bird's average velocity for the return flight?
A rock is thrown straight up into the air with an initial speed of 85 m/s at time

- A prankster flips a coin off of the Empire Building at a height of 1054 feet above the ground. The initial vertical velocity of the coin is 1.20m/s. In real life, air resistance would limit the maximum speed the coin can attain during its fall, but if air resistance were not a factor and assuming it has practically no horizontal motion, answer the following questions. (1 foot = 0.3048m) a. What would the coin's velocity be when it hits the ground? b. How long would it take to hit? c. How high would the coin be halfway through the total falling time, and how fast would it be falling then?arrow_forwardYou are on the roof of a Physics Building, 51 m above the ground. Your physics professor, who is 1.84 m tall, is approaching the building at constant speed of 1.19 m/s. If you wish to drop an egg on his head, how far should your professor be when you release the egg? Do not round the answer. Put all the decimals.arrow_forwardIn a cartoon program, Peter tosses his baby, Stewie, up into the air to keep the child entertained. Stewie reaches a maximum height of 0.613 m above the release point. Suppose the positive y axis points upward. (a) With what initial velocity was Stewie thrown? (Express your answer in vector form.) (b) How much time did it take Stewie to reach the peak height?arrow_forward
- A boy throws a stone horizontally with an initial speed of 20 m/s from the edge of a cliff. A stop watch measures the stone's trajectory time from the top of the cliff to the bottom to be 5.0 s. (a) What is the height of the cliff? (b) How far does the stone travel horizontally? (c) What is the total acceleration of the stone while it is in the air?arrow_forwardAn astronaut on the Moon (g=1.62 m/s2) throws a rock from the ground level with a speed of 32.1 km/h directly upwards. Determine the time after which the rock reaches the height equal to three quarters of its maximum height on the way down.Provide your answer with the precision of two places after the decimal.arrow_forwardA student wishes to design an experiment to show that the acceleration of an object is independent of the object's velocity. To do this, ball A is launched horizontally with some initial speed at an elevation 1.5 meters above the ground, ball B is dropped from rest 1.5 meters above the ground, and ball C is launched vertically with some initial speed at an elevation 1.5 meters above the ground. What information would the student need to collect about each ball in order to test the hypothesis?arrow_forward
- A ball is thrown from a rooftop with an initial downward velocity of magnitude vo = 4.9 m/s. The rooftop is a distance above the ground, h = 29 m. In this problem use a coordinate system in which upwards is positive. A: Find the vertical component of the velocity, vfy, in meters per second, with which the ball hits the ground. B: If we wanted the ball's final speed to be exactly 27.3 m/s, from what height, hnew (in meters), would we need to throw it with the same initial velocity? c: If the height is fixed at 29 m, but we wanted the ball's final speed to be 32.7 m/s, what would the vertical component of the initial velocity viy need to be, in meters per second?arrow_forwardA rocket is fired vertically upward with an initial velocity of 80 m/s at the ground level. Its engine then fires and it accelerated at 4m/s2 until it reaches an altitude of 1200m. At that point, the engine fail and the rocket goes into free fall. Disregard air resistance. How long was the rocket above the ground?arrow_forwardA fox locates rodents under the snow by the slight sounds they make. The fox then leaps straight into the air and burrows its nose into the snow to catch its meal.
