Physics

An object with total mass mtotal = 14.8 kg is sittingat rest when it explodes into three pieces. One piece with massm1 = 4.8 kg moves up and to the left at an angle ofθ1 = 22° above the –x axis with a speed of v1= 27.6 m/s. A second piece with mass m2 = 5.1 kg movesdown and to the right an angle of θ2 = 27° to the rightof the -y axis at a speed of v2 = 20.5 m/s.

What is the x-component of the velocity of the third piece?

What is the y-component of the velocity of the third piece?

What is the magnitude of the velocity of the center of mass ofthe pieces after the collision?

Calculate the increase in kinetic energy of the pieces duringthe explosion？
