You are working in the movie industry. The director of a western film has come up with an impressive stunt and has asked you to assist with its setup. A cowboy sitting on a tree limb is to drop vertically from rest onto his galloping horse as it passes under the limb. The horse gallops at a constant rate of 11.0 m/s along a straight line and the vertical distance between the limb and the level of the saddle is 3.57 m. (Define the point at which the cowboy's bottom and the saddle meet as (x, y) = (0,0).)
(a) You must advise the director as to the position of the horse along the line of its travel when the cowboy should begin his drop. What advice do you provide the director? (Give the magnitude of your answer in m.) m
(b) The director also asks you for advice on how much padding to put on the saddle so that the cowboy is not injured. (Assume the cowboy's flesh is compressed 3.0 cm against the saddle before coming to rest.)
The cowboy would avoid injury if the director adds at least 42.7 cm of padding to the saddle.
The amount of padding necessary to avoid injury would be too thick for the director to hide from the film's audience.
The cowboy would avoid injury if the director adds at least 3.0 cm of padding to the saddle.
No additional padding is necessary and the cowboy's body would withstand the landing without injury.

Aboxcar traveling at 12 m/s approaches a string of 5 identical boxcars sitting stationary on the track. the moving boxcar collides and links with the stationary cars and they all move off together along the track. what is the final speed of the cars immediately after the collision? (you may take the mass of each boxcar to be 18,537 kg.)

4r-134a enters the condenser of a residential heat pump at 800 kpa and 50°c at a rate of 0.022 kg/s and leaves at 750 kpa subcooled by 3°c. the refrigerant enters the compressor at 200 kpa superheated by 4°c determine (a) the isentropic efficiency of the compressor, (b) the rate of heat supplied to the heated room, and (c) the cop of the heat pump. also, determine (d) the cop and rate of heat supplied to the heated room if this heat pump operated on the ideal vapor-compression cycle between the pressure limits of 200 and 800 kpa. (0.757, 4.37 kw, 5.12, 6.18, 3.91 kw)
