Question

drive a relation between k.e and momentum

Answer 1

Kinetic energy is a stored energy and momentum is a movment dine by the object

Answer 2

$k.e = 1 \div 2mv {}^{2} \\ momentum(p) = mv \\ i \: am \: multiply \: m \: up \:and \: down \: in \: kinetic \: energy \: formula \\ so \: kinetic \: energy = m {}^{2} v {}^{2} \div 2m \: \: \: \: \: \: \: eq \: 1\\ so \: p {}^{2} = m {}^{2} v { \:}^{2} put \: in \: eq \: 1 \\ k.e = p {}^{2} \div 2m$
that is the relation between ke and momentum.
