P=F/A
A=F/P
P = 0.1 atm = 10132.5 Pa
A=4 x 10⁵/10132.5
A=39.477 m²
for one wing=39.477 : 2 = 19.739 m²
10Km South. Displacement is the total distance the subject is from the starting point.
Answer:
9 m/s
Explanation:
mass of cannon, M = 100 kg
mass of cannon ball, m = 10 kg
velocity of cannon ball, v = 90 m/s
Let the recoil velocity of cannon is V.
Us ethe conservation of linear momentum, as no external force is acting on the system, so the linear momentum of the system is conserved.
Momentum before the firing = momentum after the firing
M x 0 + m x 0 = M x V + m x v
0 = 100 x V + 10 x 90
V = - 9 m/s
Thus, the recoil velocity of cannon is 9 m/s.
