Q1. A hand grenade of total mass 5kg explodes into three pieces.Two of them, each of mass 1kg, have velocities of 8m/s with anangle of 43° between them. What is the speed of the thirdpiece?
**well the answer should be 3.9 m/s as per my HW, I just keptgetting It wrong, kindly show how to solve for this answer.
Q2. is similar
a hand grenade has a mass of 6kg and It explodes into 3 pieceseach of the same mass. two of them go off, each with a speed of 17m/s with an angle of 60 degrees between their trajectories. what isthe speed of the third?
the answer should be 29.4 (as per my homework) I just don't knowhow to solve It.
