If a projectile is fired with angle of elevation α and initial speed v. then parametric equations for its trajectory are
(See Example 13.4.5.) We know that the range (horizontal distance traveled) is maximized when α =45c. What value of α maximizes the total distance traveled by the projectile? (State your answer correct to the nearest degree.)

- Object A is travelling along a circle of radius 2, and Object B is travelling along a circle of radius 5. The object have the same angular speed. Do the objects have the same linear speed? If not, which object has the greater linear speed?arrow_forwardShooting into the Wind Using the parametric equations you derived in Problem 6. draw graphs of the path of a projectile with initial speed v0=32ft/s, fired into a headwind of =24ft/s, for the angles =5,15,30,40,45,55,60 and 75. Is it still true that the greatest range is attained when firing at 45 ? Draw some more graphs for different angles, and use these graphs to estimate the optimal firing angle.arrow_forward
