A 220g block on a 54.0cm -long string swings in a circle on a horizontal, frictionless table at 70.0 rpm. A) What is the speed of the block? m/s B) What is the tension in the string? N
A box of mass 3 units rests on a horizontal rough surface and is tied to the end of a rope. Peter pulls on the rope and exerts a force of magnitude sqrt(2g) with the rope making an angle of Pi/4 with the horizontal. Given that the box is on the point of slipping, show tha...
