Answer:
3504.4 kgm/s
Explanation:
First, convert km/hr to m/s:
19 km/hr x 1000m/1km x 1/60min x 1/60s = 5.28 m/s

p = (664 kg)(5.28 m/s) = 3504.4 kgm/s
2nd stone time = 13.0/9.8 = 1.33 seconds
distance = 0.5*9.8*1.33^2 = 8.67 meters
1st stone time = 1.33+1.5 = 2.83 seconds
distance = 0.5*9.8*2.83^2 = 39.24 meters
39.24-8.67 = 30.57 meters apart
