Which equation is true when the height of a projectile is at its maximum?

Recall that the Range equation gives the horizontal distance a projectile can be launched. 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. ?

Find 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 units

Table 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°.

A football is kicked with a speed of 30.0 m/s. Determine the two angles above the horizontal the football could be kicked to just clear the field goal post 7. Assume that the football hits the cross bar and bounces over (football goes through the point x = 60.0 m and y = 3.05 m, assuming the football is kicked from the origin. %3D %3D

A rifle that shoots bullets at 474 m/s is to be aimed at a target 46.1 m away. If the center of the target is level with the rifle, how high above the target must the rifle barrel be pointed so that the bullet hits dead center? Number i Units

In projectile motion explain why the direction of y component of velocity changes both magnitude and direction, and why the x component remain the same.
