3. Austin Luce has found an unusual way to measure the height of the school building. He throws a baseball from the top of the building with a horizontal velocity of 8 m/sec. The ball
lands 45 m from the base of the building. Calculate the height of the school building.

Achemistry student needs of 40ml diethylamine for an experiment. by consulting the crc handbook of chemistry and physics, the student discovers that the density of diethylamine is 0.7 . calculate the mass of diethylamine the student should weigh out. round your answer to significant digits.

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?
