Option B is correct ( difficulty in recovering from a stalled condition.)

Explanation:

Option B is correct ( difficulty in recovering from a stalled condition.)

If you load airplane in such manners CG has changed then it will have huge impact on the longitudinal stability. Due to this airplane would face difficulty in recovering from a stalled condition.

Stall is the phenomena in which air resistance is increased on the wings which causes decrease in lift. So it is important to remain with in CG limit put by manufacturer to avoid stall condition.

Svetach [21]

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.

(25%) Problem 3: A bullet is fired horizontally into an initially stationary block of wood suspended by a string and remains emb

Rus_ich [418]

Answer:

Thus, the initial velocity of the bullet is 507.5 m/s.

Explanation:

mass of bullet, m = 0.0085 kg

mass of block, M = 0.99 kg

Height raised, h = 0.95 m

Let the initial velocity of bullet is u and the final velocity of block and bullet system is v.

Use conservation of energy

Potential energy of bullet bock system = kinetic energy of bullet block system

$(M+m)\times g\times h = \frac{1}{2}\times \left ( M+m \right )v^{2}$

$v=\sqrt{2gh}$

$v=\sqrt{2\times 9.8\times 0.95}=4.32 m/s$

Now use conservation of linear momentum

mu = (M+m) v

0.0085 x u = (0.99 + 0.0085) x 4.32

0.0085 u = 4.314

u = 507.5 m/s

Thus, the initial velocity of the bullet is 507.5 m/s.
