Question

(a) Give one example of each of the following:

Small mass but high kinetic energy

Large mass but low kinetic energy

(b) Prove mathematically that the total mechanical energy of a freely falling body in air is

conserved.​

Answer 1

Answer:

a) ke=1/2mv^2

so off mass is less but velocity is high, a small mass may have high kinetic energy

if mass is high but velocity is low, kinetic energy of a body with high mass is less.
