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.

Athermometer is removed from a room where the temperature is 70° f and is taken outside, where the air temperature is 10° f. after one-half minute the thermometer reads 60° f. what is the reading of the thermometer at t = 1 min? (round your answer to two decimal places.) ° f how long will it take for the thermometer to reach 30° f? (round your answer to two decimal places.)

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.

What would be the strength of earth's gravitational field at a point where an 80.0 kg astronaut would experience a 80% reduction in weight
