A body is traveling at30 ms along the positive directionof, Ask an Expert

Academics

A body is traveling at3.0 m/s along the positive directionof an x axis; no net force acts on the body. An internalexplosion separates the body into two parts, each of mass3 kg, and increases the total kineticenergy by 27 J. The forward partcontinues to move in the original direction of motion.

(a) What is the speed of the rear part?

m/s

(b) What is the speed of the forward part?

m/s
