Physics

An object with total mass mtotal = 14.9 kg is sitting at restwhen it explodes into three pieces. One piece with mass m1 = 4.8 kgmoves up and to the left at an angle of θ1 = 23° above the –x axiswith a speed of v1 = 27.9 m/s. A second piece with mass m2 = 5.1 kgmoves down and to the right an angle of θ2 = 28° to the right ofthe -y axis at a speed of v2 = 20.9 m/s.

m3=5KG

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

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

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