A softball pitcher swings a ball of mass 0.244 kg around a vertical circular path of radius 59.3 cm before releasing it from her hand. The pitcher maintains a component of force on the ball of constant magnitude 30.3 N in the direction of motion around the complete path. The speed of the ball at the top of the circle is 14.7 m/s. If the ball is released at the bottom of the circle, what is its speed upon release

Steam enters an adiabatic diffuser at 150 kpa and 1208c with a velocity of 550 m/s. determine the minimum velocity that the steam can have at the outlet when the outlet pressure is 300 kpa.

Which of these is constant for all types of electromagnetic radiation in a vacuum? select one: a. wavelength b. frequency c. photon energy d. amplitude e. velocity

A5 foot by 5 foot box culvert is buried 6 feet beneath the surface of the ground. a crosssection of this very long culvert (into and out of the page) is illustrated below. assume that the soil in which the culvert is buried has the following properties: jt = 120 pcf, w = 12%, ko = 0.50, ka = 0.33, and kp = 3.00. calculate the total horizontal force per unit length of culvert (fh) felt on one of the vertical faces of the culvert.
