A 102.1 kg cannon at rest contains a 9.8 kg cannon ball. When fired, the cannon ball leaves the cannon with a speed of 88.03 m/s . What is the recoil speed of the cannon?
1 answer:
Answer:
8.45m/s = recoil speed
Explanation:
Momentum = mass • velocity
9.8kg • 88.03m/s = 102.1kg • recoil speed
862.694kg•m/s = 102.1kg • recoil speed
divide both sides by 102.1kg
8.45m/s = recoil speed

Bro the picture is too dark I can’t see do it again so I can help you
Explanation:
Assuming constant speed:
Distance = speed × time
17.8 m = (5.3 m/s) t
t = 3.36 s
A=F/m
What diagram? There isn’t one
Ideally, 576 J because energy is conserved.
