1. What are the inaccuracies which could have occurred [in your measurement of h and t) to cause potential energy, to be different from kinetic energy? Explain.​

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
