I had to throw a softball for a lab and record data. How would I solve for Initial Velocity, the angle at which it was thrown, and the Max Height? Data:
Time = 1.2s
Distance = 7.26m
Starting Height(the height at which I released the ball) = 2m

What tightening torque should be used for a hexagonal head screw (not split-bolt) on a 250 kcmil conductor?

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).

Ablue car pulls away from a red stop-light just after it has turned green with a constant acceleration of 0.5 m/s 2 . a green car arrives at the position of the stop-light 6.5 s after the light had turned green. if t = 0 when the light turns green, at what time does the green car catch the blue car if the green car maintains the slowest constant speed necessary to catch up to the blue car? answer in units of s.
