Review. The biggest stuffed animal in the world is a snake 420 m long, constructed by Norwegian children. Suppose the snake is laid out in a park as shown in Figure P3.39, forming two straight sides of a 105 angle, with one side 240 m long. Olaf and Inge run a race they invent. Inge runs directly from the tail of the snake to its head, and Olaf starts from the same place at the same moment but runs along the snake. (a) If both children run steadily at 12.0 km/h. Inge reaches the head of the snake how much earlier than Olaf? (b) If Inge runs the race again at a constant speed of 12.0 km/h. at what constant speed must Olaf run to reach the end of the snake at the same time as Inge? Figure P3.39
2. A highway is to be built between two towns, one of which lies 35.0 km south and 72.0 km west of the other. What is the shortest length of highway that can be built between the two towns, and at what angle would this highway be directed with respect to due west?
A pirate ship is 506 m away from a fort that is being defended by artillery that is sea level. The defensive cannon is capable of firing a cannon ball at 95 m/s. At what angle(s) above horizontal can the cannon fire the cannon ball so that it will hit the pirate ship?
Snow is falling vertically at a constant speed of 7.8m/s. a) At what angle from the vertical and b) with what speed do the snowflakes appear to be falling as viewed by the driver of a car traveling on a straight road with a speed of 55km/h?
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?
An archer shoots an arrow horizontal at 84m/s. When the arrow strikes the target 25m away, what is its vertical displacement ( magnituide and direction) from its original height ? ( direction as up and down)
19. What is the optimum angle that can reach the maximum range for a given projectile? Select one: a. 35 degree b. 45 degree c. 55 degree d. 65 degree
An arrow has an initial launch speed of 39 m/s If it must strike at a target 28 m away At the same angle what must the projection angle be?
The speed of a projectile when it reaches its maximum height is 0.38 times its speed when it is at half its maximum height. What is the initial projection angle of the projectile?
A science student is riding on a flatcar of a train traveling along a straight, horizontal track at a constant speed of 10.0 m/s. The student throws a ball into the air along a path that he judges to make an initial angle of 60.0° with the horizontal and to be in line with the track. The student’s professor, who is standing on the ground nearby, observes the ball to rise vertically. How high does she see the ball rise?
6. A river is 85 meters wide, and has a current speed of 5.0 m/s. A swimmer is capable of swimming at 8.0 m/sin a pool.a) If the swimmer pointed directly across the river, how far downstream would they end up aftercrossing the river? b) If the swimmer wished to traverse directly across the river, what angle should they direct theirswim?
A rocket is landing vertically downward from a point 2 miles east of an observer on the ground. What is the speed of the rocket when the angle of elevation of the observer's line of sight to the rocket is 50° and is decreasing 5° per second?
