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:
The reason why first impressions are so important is that they last well beyond that moment. This is thanks to something called the primacy effect, which means that when someone experiences something before other things in a sequence, they remember that first thing more.

Rate of speed (3 m/s north is three miles per second north, so it's a rate of speed)
Answer:
Work done is equal to 125.44 J
Explanation:
We have given mass of the student m = 80 kg
Distance moved d = 4 m
Acceleration due to gravity 
Coefficient of kinetic friction 
So normal force exerted by student 
We know that work done is equal to multiplication of force and distance
So work done
