Roque is flying a kite along the dolomite sand of Manila Bay. If the string is 45 meters, determine the rate at which the angle of elevation is changing if the horizontal distance from him to the point directly below the kite is 13 meters. Assume that he is running at a rate of 1.2 m/s; the kite is not swaying as it flies upward; and he started from rest when the kite is directly along his field of vision. A. 0.0923 rad/s B. 0.0279 rad/s C. 0.0222 rad/s D. None of these

A science student is riding on a flatcar of a train traveling along a strait, horizontal track at a constant speed of 16ˍm/s. The student throws a ball into the air along a path he judges to make an initial angle of 64° 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?
A radar-tracking dish located 2400 meters from the base of a rocket’s launching padis always aimed at the rocket at any given time. The rocket takes off and atthe instant that it is 700 meters above the ground, it is rising at a rate of 500m/s. Howfast is the angle of elevation of the rocket from the tracking dish changing at thisinstant?

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.
