bobpursley · Answer

a. speed=distance/time= 2PI*radius/time b. centripetal acc= speed^2/radius

Nicole · Answer

a. speed=distance/time= 2PI*radius/time What does 2PI mean?

Speed : Circumference is 2pi(r) So C= 1005 Speed: Distance/time 1005/36= 27.93 m/s^2

hannah bahng · Answer

just do 2pi(radius)/t circumference for distance d/t so d=circumference ye
