How much work is done on the mass by the tension

  • #1
. You swing a 55-g mass on the end of a 0.75-m
string around your head in a nearly horizontal circle
at constant speed, as shown in Figure 11-16.
a. How much work is done on the mass by the
tension of the string in one revolution?
b. Is your answer to part a in agreement with
the work-energy theorem? Explain.
my answer
a-the work is zero because the distance and Force are Orthogonal
b- I do not have answer for this question

Good.
b- I do not have answer for this question
What does the work-energy theorem say?
