As a traffic light turns green, a waiting car starts with a constant acceleration of 3.43 m/s2x. At the instant the car begins to accelerate, a
truck with a constant velocity of 35.82 m/s x passes in the next lane.
How much time does it take for the car to catch up with the truck again?
seconds (to the nearest hundredth)

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
