Answer #1

A rock is tied to a string and spun in a circle of radius 1.4 m
as shown in the figure below. The speed of the rock is 13 m/s.
(c) What is the total force on the rock directed toward the
center of its circular path? Express your answer in terms of the
(unknown) tension T in the string. (Use the following as necessary:
?.) F = (d) Apply Newton's second law along both the vertical and
the horizontal...
