Vehicle weight shifts can be backward forward. In this particular case accelerating to fast would cause a shift of weight backwards. Breaking too quickly on the other hand would cause weight to shift forward. You have seen this while in a car or a bus at the traffic light. As the vehicle breaks you are pulled forward as it starts moving you are pulled backwards.
Answer:
14.04 m/s
Explanation:
To find the velocity of the first car after the collision, we can use the equation of conservation of momentum:
m1v1 + m2v2 = m1'v1' + m2'v2'
We have the following data:
m1 = m1' = 328,
m2 = m2' = 790,
v1 = 19.1,
v2 = 13,
v2' = 15.1.
Using this data, we can find v1' (final velocity of the first car):
328 * 19.1 + 790 * 13 = 328 * v1' + 790 * 15.1
16534.8 = 328 * v1' + 11929
328 * v1' = 4605.8
v1' = 14.04 m/s
Answer:
Explanation:
mass of the astronaut including the spacesuit, 
distance of astronaut from the spaceship, d = 13 m
mass of the oxygen tank, m = 3 kg
Speed of tank with respect to spaceship, 
a)
<u>Using the conservation of linear momentum:</u>
total momentum before collision = total momentum after collision



b)
She mush hold her breath until she reaches the spaceship, i.e.



Answer:
F = 0
Explanation:
Given that,
Force acting to push a bin = 45 N
Mass of the plastic bin, m = 3 kg
The plastic bin is moving with a constant velocity.
We need to find the net force acting on the box. Constant velocity means the change in velocity is equal to 0. It means acceleration will be 0.
As a result, the force acting on the box is equal to 0.
Answer:
Explained
Explanation:
Thickness coating= t
wavelength of light λ = 500 nm
2 t =(m+0.5)λ
Here m = 0
t= λ/4
= 500/4 nm
= 125 nm
= 125×10^(-9) m
