A ball is thrown horizontally from a 11 m high building with a speed of 9.0 m/s. How far from the base of the building does the ball hit the ground?
Express the answer using two significant figures.

What statements accurately describe atoms

What is the force that opposes motion and works against the downward pull? a) friction b) gravity c) weight d) acceleration

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
