Answer:
C. They have the same change of momentum.
Explanation:
Let "m" be the mass and "v" the velocity.
According to the property of conservation of momentum, when objects 1 and 2 collide:
Therefore, one can conclude that the change in momentum (Δ(mv)) has the same magnitude but opposite sign for any two objects regardless of how much heavier one might be than the other.
They have the same change of momentum.
Answer:
The shortest distance is
Explanation:
The free body diagram of this question is shown on the first uploaded image
From the question we are told that
The speed of the bicycle is
The distance between the axial is
The mass center of the cyclist and the bicycle is behind the front axle
The mass center of the cyclist and the bicycle is above the ground
For the bicycle not to be thrown over the
Momentum about the back wheel must be zero so
=>
=>
Here
So
Apply the equation of motion to this motion we have
Where
and since the bicycle is coming to a stop
=>
Answer:
4.3 km
