Suppose there is a slight breeze so that the range equation is modified in the following way: R(0) : = sin(20) – 0.900 R Part A Use Calculus to determine the angle (in degrees) at which the projectile will reach its maximum range. ? OmazFind the x component of the vector described by "Ground control observes that the plane flies with speed 150 m/s at 40.0 degrees south of wesť"? Give your answer in m/s. Assume positive x points toward the east. Your Answer: Answer unitsTable 1. Shot velocity (V) of the projectile at an angle of 30. Two shots were made for each distance. Column 1 and 2 correspond to the throw from 1 meter away. To determine the velocity of fire of the projectile on the x-axis, use the equation: Vxo = Vo * cos 30°.
