Answer: 90000 kgm/s
Explanation:
Given that,
Momentum of car = ?
Mass of car = 1,5000 kg
Velocity of car = 6 m/s
Recall that momentum is the product of mass of the moving object by its velocity
i.e Momentum = mass x velocity
Momentum = 15000kg x 6m/s
= 90000kgm/s
Thus, the momentum of the car is 90000 kgm/s
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: elastic potential energy
Explanation:
A because that is the answer
