A plastic ball in a liquid is acted upon by its weight and by a buoyant force. The weight of the ball is 3.8 N. The buoyant force has a magnitude of 5.0 N and acts vertically upward. At a given instant, the ball is released from rest. The acceleration of the ball at that instant, including direction, is closest to: O 1.5 m/s², upward 1.5 m/s2, downward O zero 3.1 m/s², upward 3.1 m/s², downward

A ball is projected upward at time initial velocity of the ball is 914 / ground is closest to: O.96 m/s O-77 m/s O-38 m/s -115 m/s O-58 m/s t= 0.0 s, from a point on a roof 90 m above the ground. The ball rises, then falls and strikes the ground. The Consider all quantities as positive in the upward direction. The velocity of the ball when it is 45 above the
