Answer:
754.6 m
Explanation:
The GPE (Gravitational potential energy) of an object with respect to the ground is given by

where
m is the mass of the object
g = 9.8 m/s^2 is the acceleration due to gravity
h is the heigth above the ground
Here we have
m = 12,400.05 kg is the mass
GPE = 91,700,000.00J is the GPE
Solving the formula for h, we find the heigth:

1) 211m/s
2)240<span>°
3)759,600m or 759.6 km</span>
Answer:
<h3>
The coefficient of kinetic friction between the puck and the ice is
0.12</h3>
Explanation:
Given :
Initial speed 
Displacement
m
From the kinematics equation,

Where
final velocity, in our example it is zero (
),
acceleration.


From the formula of friction,

Minus sign represent friction is oppose the motion
Where
( normal reaction force )
( ∵
)
So coefficient of friction,


Therefore, the coefficient of kinetic friction between the puck and the ice is
0.12 .
