Calculate the average height of the marshmallow for each spoon distance.

Calculate the maximum gravitational potential energy using the average height and Eg= mgh

Determine the value for maximum kinetic energy (all the KE turned into GPE) (KE = GPE).

Calculate the velocity of the marshmallow when it first left the spoon. (from KE =1/2mv2

An air cannon is used to shoot marshmallows down the 500 hall ofthe Albert Robin campus building. The muzzle velocity is 100 metersper second. Neglect air resistance.
A. Given an initial launch angle of 0 degrees and an initial heightof 1.5 meters, how far down the hallway does the marshmallow travelbefore striking the floor?
B. Show that the maximum range would be achieved by launching at 45degrees.
C. What is the maximum range that the marshmallow can belaunched?
D. What two angles can be used to launch the marshmallow ½ themaximum distance? Assume there is no problem with overheadobstacles.

Calculate the gravitational potential energy and kinetic energy for each position marked. 

A 2.56-kg rock is released from rest at a height of 18.6 m. Ignore air resistance and determine (a) the kinetic energy at 18.6 m, (b) the gravitational potential energy at 18.6 m, (c) the total mechanical energy at 18.6 m, (d) the kinetic energy at 0 m, (e) the gravitational potential energy at 0 m, and (f) the total mechanical energy at 0 m.
