A 6.10 kg object falls freely (ignore air resistance), after being dropped from rest. Determine the initial kinetic energy (in J), the final kinetic energy (in J), and the change in kinetic energy (in J) for the following.

(a)

the first meter of the fall

initial kinetic energy J final kinetic energy J change in kinetic energy J

(b)

the second meter of the fall

initial kinetic energy J final kinetic energy J change in kinetic energy J
