(Q) a 108 cm, 0.73kg golf club is swung for 0.5s with a constant acceleartion of 10 rad/s (squ). What os the linear momentum of the club head when it impacts the ball? Known: H= 108cm = 1.8m m = 0.73 kg =7.16N t = 0.5s [itex]\alpha[/itex]= 10 rad/s (squ) I know momentum = mass x velcoity So velcotiy = d/t.... (so i need to find the dispalcement) But Im thorwn but the angular accelertion o 10 rad/s(squ) The only thing I can think of is using 2(pi)r with r being the 1.8m? Any sugegstion where to go from here ??
