When Paris was shelled from 100 km away with the WWI long-range artillery piece “Big Bertha,” the shells were fired at an angle greater than 45º to give them a greater range, possibly even twice as long as at 45º. Does that result mean that the air density at high altitudes increases with altitude or decreases?
An archer fish spies a meal of a grasshopper sitting on a long stalk of grass at the edge of the pond in which he is swimming. The fish is to successfully spit at and strike the grasshopper, which is 0.200 m away horizontally and 0.435 m above his mouth. What angle (in degrees) above the horizontal must he spit? Assume vfy = 0.
At t=0, a particle is projected with a speed Vo at angle theta from a cliff point H=100m from ground level as shown. It is seen at time t=2s, having a velocity v(t2)=8i ‐ 11j m/s according to the coordinate system shown. You must use this coordinate system and origin O. a)Find V o, and theta o. b) If the cliff height is H=100m, write a numerical expression for (t2) in unit vector notation. You must use the origin O and then draw r (t2) on the diagram. c)Find R, the horizontal distance the object has traveled when it reaches its highest point.
Imagine you want to measure the height of an inaccessible mountain peak on an island in the South Pacific. First, you line up your boat so it is due west of the peak, and then find that the peak is an angle of 12 degrees up from the horizon. Next, you move your boat a displacement of 25km, 37 degrees south of east. How tall is the peak of the mountain?
A pirate has buried his treasure on an island with five trees located at the points (30.0 m, 20.0 m), (60.0 m, 80.0 m). (10.0 m, 10.0 m), (40.0 m, 30.0 m), and (70.0 m, 60.0 m), all measured relative to some origin, as shown in Figure P3.46. His ships log instructs you to start at tree A and move toward tree B, but to cover only one-half the distance between A and B. Then move toward tree C, covering one-third the distance between your current location and C. Next move toward tree D, covering one-fourth the distance between where you are and D. Finally move toward tree E, covering one-fifth the distance between you and E, stop, and dig. (a) Assume you have correctly determined the order in which the pirate labeled the trees as A, B, C, D, and E as shown in the figure. What are the coordinates of the point where his treasure is buried? (b) What If? What if you do not really know the way the pirate labeled the trees? What would happen to the answer if you rearranged the order of the trees, for instance, to B (30 m, 20 m), A (60 m, 80 m), E (10 m, 10 m), C (40 m, 30 m), and D (70 m, 60 m)? State reasoning to show that the answer does not depend on the order in which the trees are labeled. Figure P3.46
Check Your Understanding A cave diver enters a tong underwater tunnel. When her displacement with respect to the entry point is 20 m, she accidentally drops her camera, but she doesn’t notice it missing until she is some 6 m farther into the tunnel. She swims back 10 m but cannot find the camera, so she decides to end the dive. How far from the entry point Is she? Taking the positive direction out of the tunnel, what is her displacement vector relative to the entry point?

A golfer on level ground attempts to drive a golf ball across a 50 meter wide pond by hitting the ball so that it travels initially at 25m/s at an angle of 45 degrees to the horizontal plane. How far will the golf ball travel?
One of the most amusing things a person can experience is that in certain parts of the world a still car on neutral going uphill when its brakes are released. Such occurrences are even broadcast on TV. Can this really happen or is it a bad eyesight? How can you verify if a road is really uphill or downhill?
A swimmer heads directly across a river, swimming at 1.10 m/s relative to still water. He arrives at a point 50.0 m downstream from the point directly across the river, which is 75.0 m wide. What is the speed of the river current?What is the swimmer's speed relative to the shore? In what direction should the swimmer head so as to arrive at the point directly opposite his starting point? Express your answer in terms of the angle with respect to a line drawn directly across the river.
using analytical techniques andchange the second leg of the walk to 25.0 m straight south.(This is equivalent to subtracting B from A —that is, findingR′ = A – B ) (b) Repeat again, but now you first walk25.0 m north and then 18.0 m east. (This is equivalent tosubtract A from B —that is, to find A = B + C . Is thatconsistent with your result?)
