A distance between pitcher and batter = 18.39m A ball's velocity u=41.52m/s diameter D=0.074m mass m=145.5g Air's density rho = 1.18kg/m^3 viscosity μ = 1.86E-05 Pa*s kinetic viscosity ν= 1.58E-05 m^2/s. In the coordinate system, following thrown baseball, the origin is center of the ball. x-axis is the direction of the thrown ball, z-axis is rotation axis. Required:
Determine the scale of the distance the baseball moves to y-axis direction, by rotation, when the ball meets the batter.

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.

At very high pressures, gases become and will eventually a) more dense; become hotter b) more dense; change to a liquid or solid c) less dense; combust d) less dense; turn into a liquid

Refrigerant-134a flows through a carnot heat pump cycle at 0.5 kg/s. it is known that the maximum absolute temperature in the cycle is 1.1 times the minimum absolute temperature, and the net power input to the cycle is 2.5 kw. if the refrigerant changes from a saturated vapor to a saturated liquid during the heat rejection process, determine the maximum magnitude of the enthalpy of vaporization for this process in kj/kg (with 3 significant figures).
