- An athlete whose event is the shot put releases the shot with the sameinitial velocity but at different angles. The figure shows the parabolic paths for shots released at angles of 35° and 65°. Solve the following based on the functions that model the parabolic paths. When the shot whose path is shown by the red graph is released at an angle of 65°, its height, g(x), in feet, can be modeled by g(x) = -0.04x2 + 2.1x + 6.1, where x is the shot’s horizontal distance, in feet, from its point of release. Use this model to solve the below parts (a) through (c) and verify your answers using the red graph. a. What is the maximum height, to the nearest tenth of a foot, of the shot and how far from its point of release does this occur? b. What is the shot’s maximum horizontal distance, to the nearest tenth of a foot, or the distance of the throw? c. From what height was the shot released?The horizontal distance or range (R) of an object thrown at an angle θ from the horizontal is represented by the equation below where v0 is the initial velocity as the object leaves the hand, in feet per second. If v0 = 2500 feet per second and θ is changed from 13° to 14°, use differentials to approximate the change in range, in feet.Write the type of projectile motion?
