Question

A gold atom has a' niass of 3.287 x 1025
kg and is at rest. It emits an alpha
particle that has a mass of 6.646 x 102kg. In this process, the gold atom is
transformed into an iridium isotope. The alpha particle has a speed of
3.40 x 10 m/s.
a) what is the absolute value of the momentum of the alpha particle?
b) What is the absolute value of the momentum of the iridium isotope after the emission of the
alpha particle?
c) What is the speed of the iridium isotope after the emission process?

The equation a = Fnet / m is valid in any dimension. That is, a = Fnet / m implies ax = Fnet x / m and ay = Fnet y / m. Similarly, the law of conservation of momentum is valid in any dimension. pA0 + pB0 = pA + pB implies pA0x + pB0x = pAx + pBx and pA0y + pB0y = pAy + pBy.Standard cue balls have masses of 170 grams, while numbered billiard balls have masses of only 160 grams.
