Physics Problem a. What is the horizontal component of the arrow’s velocity right before it hits the ground? Show your work.

b. What is the time of flight of the arrow? (Remember the time of flight is the time the arrow is in the air from the launch to it striking the ground.) Show your work.

c. What is the horizontal displacement of the arrow from the time it is launched until the moment it hits the ground? Show your work.

d. Another arrow is shot by the archer. The initial velocity of this arrow is 19.1 m/s at an angle of 40 degrees above the horizontal and the arrow is shot from a height of 1 m above the ground. Answer the following questions based on the assumptions that the arrow is a projectile and that air resistance can be ignored. What is the horizontal component of the arrow’s velocity right before it hits the ground? Show your work.

e. What is the maximum height above the ground for this arrow? Show your work.

f. What is the vertical component of the arrow's velocity right before it hits the ground? Show your work

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.

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.
