Question

an object with total mass mtotal=14.4 kg is sitting at rest when it explodes into three pieces one piece with mass m=4.7 kg moves up and to the left at an angle of 18 degrees above the -x axis with a speed of v1=26.1 m/s a second piece with mass m2=5.4 kg moves down and to the right an angle of 23 degrees to the right of the -y axis at a speed of v2=22.7 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? calculate the increase in kinectic energy of the pieces during the exsplosion?

Explanation / Answer

theta? = 162
