Afootball is kicked off with an initial speed of 64 ft/s at a projection angle of 45o. a receiver on the goal line 60 yd away in the direction of the kick starts running to meet the ball at that instant. calculate his average speed if he is to catch the ball just before it hits the ground. neglect air resistance.

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
