A potato of mass 0.150 kg is tied to astring with length 2.10 m, and theother end of the string is tied to a rigid support. The potato isheld straight out horizontally from the point of support, with thestring pulled taut, and is then released.
a) What is the speed of the potato at the lowest point of itsmotion?
b) What is the tension in the string at this point?
