An explosion blows a rock into 3 parts. Two peices go off at right angles to eachother, a 1.0 kg piece at 12 m/s and a 2.0 kg piece at 8 m/s. The third piece flies off at 40 m/s.(adsbygoogle = window.adsbygoogle || []).push({});

a) Draw a vector diagram to show the direction in which the third piece goes.

I don't know how I can determine which direction it goes

b) What is its mass?

I don't know how I can get this if I am unable to determine the total momentum.
