- A javelin thrower standing at rest holds the center of the javelin behind her head, then accelerates it through a distance of 70 cm as she throws. She releases the javelin 2.0 m above the ground traveling at an angle of 30 degrees above the horizontal. Top-rated javelin throwers do throw at about a 30 degree angle, not the 45 degree you might have expected, because the biomechanics of the arm allow them to throw the javelin much faster at 30 degree than they would be able to at 45 degree. In this throw, the javelin hits the ground 59 m away.arrow_forwardA particle travels in a circular orbit of radius 10 m.
