I'm having some issues understanding my physics homework. It doesnt look like what we were doing in class and I dont think I'm using the right formulas. I need some help with a & b, attached.

Step 1

(a)

(i) Point P, where the speed is maximum is located at the lowest point on the roller coaster. At the lowest point potential energy is lowest and hence kinetic energy is maximum.

Step 2

(ii) Write the expression for conservation of energy at point A and P

Step 3

Substituting th...
