A projectile is launched with V0 = 7.6 m/s and initial angle = 1.27 radians above the horizontal. What is the initial horizontal component of the projectile velocity in miles per hour?

The horizontal component is  

Explanation:

A diagram illustrating the projection is  shown on the first uploaded image  (from  IB Maths Resources from British international school Phuket )

From the question we are told that  

    The initial velocity is  

      The angle of projection is  

The  horizontal component of this  projectile  velocity is  mathematically represented as

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
