If v = (3i+4j+5k)ms^(-1) is the instan-taneous velocity of a body of mass 1.50 kg. calculate its kinetic energy.

If v = (3i+4j+5k)ms^(-1) is the instan-taneous velocity of a body of m

1.	If v = (3i+4j+5k)ms^(-1) is the instan-taneous velocity of a body of mass 1.50 kg. calculate its kinetic energy.
Answer» SOLUTION :`V=(3i+4j+5k)MS^(-1)M=1.5kg` KINETIC ENERGY K.E = `(1)/(2) mv^(2)` `=(1)/(2)1.5(3i+4j+5k).(3i+4j+5k,)=37.5` joules
