The rocket will cover distance in 4. 5 s. Acceleration can be defined as the change in velocity.
<h3>What is acceleration?</h3>
Acceleration can be defined as the change in speed or the direction of the object.
From kinamatic equation:
Where,
- final velocity = 445 m/s
- initial valocity = 0 m/s
- acceleration = 99. 0 m/s²
- time = 4. 50 s
Put the values in the formula,
Therefore, the rocket will cover distance in 4. 5 s.

Answer:
i) 5 /
ii) 54
iii) 54
Explanation:
i) ⇒
= 5² ÷ 5 = 5
ii) ⇒
= 108 ÷ 10 = 10.8
,
⇒
10.8 × 5 = 54
iii) F1 = F2 = 54
a) The mass of the ship is
b) The ship has a larger momentum than the shell
Explanation:
a)
The momentum of an object is given by:
where
m is the mass of the object
v is its velocity
For the ship in this problem, we have
is the momentum
is the velocity
Solving for m, we find the mass of the ship:
b)
The momentum of the artillery shell is given by
where
m is its mass
v is its velocity
For the shell in this problem,
m = 1100 kg
v = 1200 m/s
Substituting,
So, we see that the ship has a larger momentum.
