A dart hits a dartboard and stops in 0.060\ \text s0.060 s0, point, 060, space, start text, s, end text. The net force on the dart is 14\ \text N14 N14, space, start text, N, end text during the collision. What is the magnitude of the change in momentum of the dart?

With i really need the correct answer!

This is the substance(s) formed in a chemical reaction.

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
