Answer:
The percentage of the weight supported by the front wheel is A= 19.82 %
Explanation:
From the question we are told that
The center of gravity of the plane to its nose is
The distance of the front wheel of the plane to its nose is
The distance of the main wheel of the plane to its nose is
At equilibrium the Torque about the nose of the airplane is mathematically represented as
Where m is the mass of the airplane
is the weight of the airplane supported by the main wheel
So
Substituting values
Now the weight supported at the frontal wheel is mathematically evaluated as
Substituting values
Now the weight of the airplane is = mg
Thus percentage of this weight supported by the front wheel is 19.82 %
Answer:
s₁ = 0.022 m
Explanation:
From the law of conservation of momentum:
where,
m₁ = mass of hockey player = 97 kg
m₂ = mass of puck = 0.15 kg
u₁ = u₂ = initial velocities of puck and player = 0 m/s
v₁ = velocity of player after collision = ?
v₂ = velocity of puck after hitting = 48 m/s
Therefore,
negative sign here shows the opposite direction.
Now, we calculate the time taken by puck to move 14.5 m:
Now, the distance covered by the player in this time will be:
<u>s₁ = 0.022 m</u>
