(a) Another airplane is flying in a jet stream that is blowing at 45.0 m/s in a direction 20° south of east (as in Exercise 3.58). Its direction of motion relative to the Earth is 45.0° south of west, while its direction of travel relative to the air is 5.00° south of west. What is the airplane's speed relative to the air mass? (b) What is the airplane's speed relative to the Earth?
A bird embarks on the journey of winter migration from her nest. She starts by ﬂying 65.0 km due south. She then heads 55.0 ̊ south of east for 45.0 km. She ﬂies the last portion of her journey heading 35.0 ̊ south of west for 83.0 km. a) How far from the nest does the bird end up at the end of her journey? Give your answer to 3 signiﬁcant ﬁgures. b) In what direction is the nest, relative to the bird’s ﬁnal position? Give your answer as an angle, to the nearest degree.
A football quarterback is moving straight backwards at a speed of 2.9m/s when he throws a pass to a player 22 m straight downfield. The ball is thrown at an angle of 21 degrees relative to the ground and is caught at the same height as it is released. What is magnitude of the initial velocity of the ball relative to the quarterback in m/s? What angle above the horizontal does the initial velocity of the ball relative to the quarterback make? Give your answer in degrees.
Arugby player runs with the ball directly toward his opponent's goal, along the positive direction of an x axis. He can legally pass the ball to a teammate as long as the ball's velocity relative to the field does not have a positive × component. Suppose the player runs at speed 4.5 m/s relative to the field while he passes the ball with velocity O Bp relative to himself. If O Bp has magnitude 6.4 m/s, what is the smallest angle it can have (relative to the positive direction of the x axis) for the pass to be legal?
What kinematic equation/s would you use to help calculate the range of a projectile launched horizontally, and what variables from these equations must you know to accurately calculate range?
You take a three-day hiking. On the first day, you travel 5.0 km heading East. On the second day you’ve enjoyed the scenery so much that you forgot to take note how far you have walked and in what direction. On the third day, after wandering for 8.5 km and in the direction 37o South of West, you find yourself in the base camp where you have started (which means the total displacement is zero). Determine your displacement during the second day of your trip.
A diver explores a shallow reef off the coast of Belize. She initially swims d1 -> = 80.7 m north, makes a turn to the east and continues for d2-> =185 m, then follows a big grouper (a kind of fish) for d3-> = 80. 9 m in the direction Θ = 30.8° north of east. Finally, she swims d4=179.8 m south. What is the straight-line distance between her initial and final positions in m? Can you explain how you got your answer in detail?
Mt. Asama, Japan, is an active volcano. In 2009, an eruption threw solid volcanic rocks that landed 1 km horizontally from the crater. If the volcanic rocks were launched at an angle of 44° with respect to the horizontal and landed 905 m below the crater, find the following. (a)their initial velocity (Enter the magnitude in m/s.) (b)their time of flight (in s)
Two passenger trains are passing each other on adjacent tracks. Train A is moving east with a speed of 13m/s, and train B is traveling west with a speed of 28 m/s. (a) What is the velocity (magnitude and direction)of train A as seen by passengers in train B? (b) What is the velocity (magnitude and direction) of train B asseen by passengers in train A?
PROBLEM:In a basketball tournament, a tall player shoots the ball so that it leaves his hands at an initial speed of 35.0m/s and with an estimated an angle of 50.1o. Neglect the height of the basketball player, a. Determine the location of the ball and its velocity (magnitude and direction) at t = 2.00s.b. Determine the time when the ball reaches the highest point of its path and its vertical distance at that time.c. Determine the range from initial point to its final position.
A boy stands at the edge of a bridge above a river. In both of the following scenarios, a stone is thrown over the edge of the bridge by the boy at a speed of 12.0 m/s and leaves his hand at exactly 20.0 m above the surface of the water. (a) If he throws the stone straight up first, how long does it take to hit the water? (b) If he throws the stone straight down, how long does it take to hit the water? (Use kinematic equations to solve.)
A 1.00 km wide river is flowing uniformly due South at 5.00 km/h. You want to drive your boat from the west shore (A) to a point on the other shore due East from your initial point (B). Your boat's speed relative to the water is 10.0 km/h. a.) In what direction (expressed using points on the compass) should the boat be pointed so that it's net velocity relative to the shore is due East? b.) How long will it take to cross the river that way?
