A bat strikes a 0.145-kgkg baseball. Just before impact, the ball is traveling horizontally to the right at 47.0 m/sm/s ; when it leaves the bat, the ball is traveling to the left at an angle of 29.0 ∘∘ above horizontal with a speed of 59.0 m/sm/s . The ball and bat are in contact for 1.71 msms . Part A Find the horizontal and vertical components of the average force on the ball. Let +x+x be to the right and +y+y be upward Express your answers using three significant figures separated by a comma.

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
