An object m of mass m=1kg is attached to a string that passes through a hole in the center of a table. The object m moves in a circle of radius r=1.3m. An object M of mass M=2.1kg is tied to the other end of the string, and hangs vertically beneath the table. Assuming the ...

The height(H) of an object that has been dropped or thrown in the air is given by: H(t)=-4.9t^2+vt+h t=time in seconds(s) v=initial velocity in meters per second (m/s) h=initial height in meters(m) H=height h=initial height I didn't make this clear on the last post sorry. A ...
