Answer:
The coefficient of rolling friction will be "0.011".
Explanation:
The given values are:
Initial speed,
then,
Distance,
s = 18.2 m
The acceleration of a bicycle will be:
⇒
On substituting the given values, we get
⇒
⇒
⇒
⇒
As we know,
⇒
and,
⇒
⇒
On substituting the values, we get
⇒
⇒
Answer:
sum of all forces on the air plane must be ZERO
So both forces must be of same magnitude
Explanation:
As we know that airplane is moving with uniform speed is horizontal plane is a straight line
so the motion of the air plane is uniform without any acceleration
So we will have
acceleration must be zero
now by Newton's law
so sum of all forces on the air plane must be ZERO
