## Homework Statement

A small block of mass m = 1.3 kg slides, without friction, along the loop-the-loop track shown. the block starts from the point P at rest a distance h = 52.0 m above the bottom of the loop of radius R = 18.0 m.

A)What is the kinetic energy of the mass at the point A on the loop?

B)What is the magnitude of the acceleration of the mass at the point A of the loop?

C)What is the minimum height h for which the block will reach point A on the loop without leaving the track?

## Homework Equations

F=ma

KE=1/2mv^2

PE=mgh

## The Attempt at a Solution

I am unsure how to go about this problem. Can someone help me out and walk me through it Please! I guess we can just start with part A and work our way from there.
