two blocks A and B of equal masses of 1 kg are moving in opposite direction with constant speed of 2m/s and 1m/s respectively.then the minimum kinetic energy in joules,of the two block system that can be noted by an observer is a) 0 b) 5/2 c) 9/4 d) 9/2 e) none of these two blocks A and B of equal masses of 1 kg are moving in opposite direction with constant speed of 2m/s and 1m/s respectively.then the minimum kinetic energy in joules,of the two block system that can be noted by an observer isa) 0b) 5/2c) 9/4d) 9/2e) none of these
Since kinetic energy is the sacalar direcn.s doesn’t matters.Hencce total kinetic energy for the system is=>0.5*1*4 + 0.5*1*1=> 2 + ½=> 5/2 Joule.
