A ball is thrown downward from the top of a 14.7-m high building with an initial speed of 30.1 m/s. The
velocity of the ball as it hits the ground is:

Electric charge is uniformly distributed inside a nonconducting sphere of radius 0.30 m. the electric field at a point p, which is 0.50 m from the center of the sphere, is 15,000 n/c and is directed radially outward. what is the maximum magnitude of the electric field due to this sphere
