Question:

One of the highlights of Sharika's concert is her daredevil swan dive into the audience from a height of 2 m above the crowd's outstretched hands. If her mass is 60 kg, and the time of her dive is defined as t = 0,

(a) What is her initial potential energy relative to U = 0 at the position of the crowd's hands?

(b) From Newton's laws, find the distance she has fallen and her speed at t = 0.20 s.

(d) Find her kinetic energy and speed just as she reaches the hands of the crowd in the mosh pit.
