A projectile is launched with a linear momentum of 320 kg m/s and a kinetic energy of 1,112 J. What is the mass of the projectile in kilograms? Please round your answer to two decimal places.An my = 2.0 kg steel ball is initially moving to the right at a velocity of V1; = +10 m/s. The ball strikes an m2 = 3.0 kg steel ball that is initially at rest. The collision is elastic. After the collision, the velocity of my is Vif = -2.0 m/s. (a) What is the velocity of m2 after the collision, i.e. Voy? (b) How much kinetic energy did the ball with mass my lose
