The fastest pitched baseball was clocked at 47 m/s. assume that the pitcher exerted his force (assumed to be horizontal and constant) over a distance of 1.0 m, and a baseball has a mass of 145 g. a) draw a free-body diagram of the ball during the pitch. the ball is moving to the right.
b) what force did the pitcher exert on the ball during this record-setting pitch?
c) estimate the force in part b as a fraction of the pitcherâs weight. assume that the pitcher has a mass of 84 kg.

Air conditioners not only cool air, but dry it as well. suppose that a room in a home measures 5.0mĂ9.0mĂ2.4m . if the outdoor temperature is 30 âc and the vapor pressure of water in the air is 85 % of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? the vapor pressure for water at 30 âc is 31.8 torr.
