Asoftball is tossed into the air upward from a first floor balcony. the distance of the ball above the ground at any time is given by the function, distance function. jpg, where h(t) is the height of the softball above the ground (in feet) and t is the time (in seconds). what was the maximum height, in feet, of the softball above the ground after it was thrown?

Aspring has a relaxed length of 33 cm (0.33 m) and its spring stiffness is 6 n/m. you glue a 76 gram block (0.076 kg) to the top of the spring, and push the block down, compressing the spring so its total length is 15 cm. you make sure the block is at rest, then at time t=0 you quickly move your hand away. the block begins to move upward, because the upward force on the block by the spring is greater than the downward force on the block by the earth. calculate y vs. time for the block during a 0.09-second interval after you release the block, by applying the momentum principle in three steps each of 0.03-second duration.
