Answer:
a) F = - 6.75 10³ N, b) F = 1.35 10⁶ N
Explanation:
To calculate the force we can use the relation between the impulse and the moment
I = Δp
F t = m - m v₀
v_{f} = 0
F = -m v₀ / t
To calculate the time, let's use kinematics
a) Passenger with seat belt and airbag, braking distance x = 1 m
v² = v₀² - 2 a x
a = v₀² / 2x
a = 15²/2 1
a = 112.5 m / s²
v = v₀ - a t
t = v₀ / a
t = 15 / 112.5
t = 0.1333 s
Let's find the average strength
F = - 60 15 / 0.1333
F = -6750 N
F = -6.75 10³ N
b) Passenger without seat belt or airbag braking distance x = 5 mm = 0.005 m
a = v₀² / 2x
a = 15²/2 0.005
a = 22,500 m / s²
t = v₀ / a
t = 15/22500
t = 6.6667 10⁻⁴ s
The average strength is
F = - 60 15 / 6.6667 10⁻⁴
F = 1.35 10⁶ N
The horizontal distance traveled below the table's edge is 29.4 cm.
The given parameters;
- <em>mass of the bullet, = 15 g = 0.015 kg</em>
- <em>speed of the bullet, = 630 m/s</em>
- <em>mass of the block, = 4.9 kg</em>
The final velocity of the bullet-block system is calculated as follows;
The time for the bullet-block system to reach the ground from the table is calculated as follows;
The horizontal distance traveled below the table's edge is calculated as follows;
Thus, the horizontal distance traveled below the table's edge is 29.4 cm.

Answer:
16921
Explanation:
Usually, if and when the truck does lose part of its load, or load gets cut into half, then it's momentum gets reduced to half of the original momentum. This is because, from the definition of momentum, we understand that it's the multiplication of mass and velocity. This means that if the mass gets reduced to half, then the total momentum goes ahead to be reduced to half just as well.
New momentum = 1/2 * 33842
New momentum = 16,921 kg∙m/s.
Answer:
Consult not your fears but your hopes and your dreams. Think not about your frustrations, but about your unfulfilled potential. Concern yourself not with what you tried and failed in, but with what it is still possible for you to do.
