Suppose it is launched upward at 45掳 above the horizontal plane. How fast is it moving at the top of its curved trajectory?Suppose it is launched upward at 45掳 above the horizontal plane. How fast is it moving at the top of its curveAt the top of any trajectory, a projectile has 0 vertical velocity. Neglecting air resistance, it has exactly the same horizontal velocity that it began with.
