Answer:
F = - 3.56*10⁵ N
Explanation:
To attempt this question, we use the formula for the relationship between momentum and the amount of movement.
I = F t = Δp
Next, we try to find the time that the average speed in the contact is constant (v = 600m / s), so we say
v = d / t
t = d / v
Given that
m = 26 g = 26 10⁻³ kg
d = 50 mm = 50 10⁻³ m
t = d/v
t = 50 10⁻³ / 600
t = 8.33 10⁻⁵ s
F t = m v - m v₀
This is so, because the bullet bounces the speed sign after the crash is negative
F = m (v-vo) / t
F = 26*10⁻³ (-500 - 640) / 8.33*10⁻⁵
F = - 3.56*10⁵ N
The negative sign is as a result of the force exerted against the bullet
the independent variable is what you're testing or changing in an experiment, so the answer is the temperature of the ball when its dropped.
i hope that helped <3
Answer:
Florida's Cape Canaveral was central to the US victory in the space race. An isolated air force base was in Cape Canaveral near the ocean. This location allowed NASA scientists to test rockets freely.

Answer:
Just 3
Explanation:
I believe the other two are incorrect
Answer:
1600 kg
Explanation:
use the formula p=mv. p=3200, v=2. Plug in and rearrange.
3200=(m)(2)
m= 3200/2
m=1600
