In slow pitch softball, the pitcher pitches the ball to the batter in a high arc. suppose the ball leaves the pitchers hand when it is 2.5 feet above the ground with an upward velocity of 27 ft/s. the batter hits the ball when it is 3.5 feet above the ground. how much time elapses between the pitch and the hit? (meant to be a math question)

Aclarinetist, setting out for a performance, grabs his 3.350 kg clarinet case (including the clarinet) from the top of the piano and carries it through the air with an upward force of 24.65 n. find the case's vertical acceleration. indicate an upward acceleration as positive and a downward one as negative.

How does an observation about an object differ from an inference about that object

The safe load, l, of a wooden beam of width w, height h, and length l, supported at both ends, varies directly as the product of the width and the square of the height, and inversely as the length. a wooden beam 4 inches wide, 9 inches high, and 240 inches long can hold a load of 6810 pounds. what load would a beam 3 inches wide, 8 inches high, and 144 inches long, of the same material, support? (round off your answer to the nearest integer.)
