(5 pts) If the object can reach a speed of 2m/s, what is its kinetic energy? (If you don't have a scaler,
estimate the mass of the object in kg)
KE= | mv2

What is the relationship between the direction of motion of the balloon and the wind currents

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

The amount of potential energy possessed by an elevated object is equal to what?
