An object of mass m, initially moving at 6.44 along the x-axis, explodes into two pieces. The first piece, 83.6 percent of the mass, moves along the negative x-axis at 7.63 m/s. Find the speed, in m/s, of the other piece right after the explosion.
Homework Answers
using conservation of momentum
m v = m1 v1 - m2 v2
m * 6.44 = ( 1 - 0.836) m v1 - 0.836 m * 7.63
v1 = 78.16 m/s

An object of mass 4m is initially at rest. It breaks into three parts, two of mass m and one of mass 2m. After the explosion, one of the object of mass m moves along the positive y-axis with a speed of 10 m/s and the other one of mass m moves along the negative x-axis. Find the magnitude and the direction of the velocity of 2m after the explosion.
