Which choice contains the same root word in three different parts of speech. Position 1 is 250 meters above the ground (y=250 m), and since this is the initial position, t=0, and the initial velocity is v y =0.Position 2 is on the ground (y=0), and we do not know the time and velocity at this point. : //web.pa.msu.edu/courses/2012summer/phy231/lectures/section_2/ch10_1_S2_pre.pdf '' > Week 9 Rotational Dynamics: Atwood 's Machine < /a > 40 frictionless that.
