A 4.0-kg mass has a velocity of 4.0 m/s, east when it explodes into two 2.0-kg masses. After theexplosion one of the masses has a velocity of 3.0 m/s at an angle of 60° north of east. What is themagnitude of the velocity of the other mass after the explosion?a. 7.9 m/sb. 8.9 m/sc. 7.0 m/sd. 6.1 m/se. 6.7 m/s

The magnitude of the velocity of the other mass can be calculated using given steps:Given:
