POESR A science student is riding on a flatcar of a train traveling along a strait, horizontal track at a constant speed of 15 m/s. The student throws a ball into the air along a path he judges to make an initial angle of 67° with the horizontal (toward the rear of the car) 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. With what initial speed does the professor see the ball rise? 10. 38.14 m/s D. 36.74_m/s 33_m/s 35.34 m/s E. 31.39 m/s F. 34.16 m/s A. B. C.

A fireman d = 50.0 m away from a burning building directs a stream of water from a ground-level fire hose at an angle of i = 30.0 above the horizontal as shown in Figure P3.18. If the speed of the stream as it leaves the hose is vi = 40.0 m/s, at what height will the stream of water strike the building? Figure P3.18
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 0.395 m above his mouth. A) What angle (in degrees) above the horizontal must he spit? (In degrees)
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.
A projectile is fired vertically from point A with an initial speed of 215 ft/sec. Relative to an observer located at B, at what times (find two times t1 < t2) will the line of sight to the projectile make an angle of 23° with the horizontal? Compute the magnitude of the speed of the projectile at each time, and ignore the effect of aerodynamic drag on the projectile. Calculate the height h when the projectile is at point C.

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?
