You serve a volleyball with a mass of 0.77 kg. The ball leaves your hand with a velocity of 2.33 m/s. Calculate the joules of kinetic energy of the ball.

A2k pendulum has a speed of 1 m/s at a height of 1/2 meter

Air conditioners not only cool air, but dry it as well. suppose that a room in a home measures 5.0m×9.0m×2.4m . if the outdoor temperature is 30 ∘c 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 ∘c is 31.8 torr.

What is part of a line has one endpoint and continues in one direction?
