Compare the total energy of the bowling ball at each of the three points. a. Do the potential or kinetic energy stay the same as the bowling ball falls?
b. What happens to the potential energy that the bowling ball started with as it falls?
c. Does the total amount of energy that the bowling ball has stay the same as it falls?

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
