To enable life, this most special of attributes, planet earth has a number of ideal features it is unique among other planets in our solar system for having water in its liquid form at the surface in an conducive to life evolving
Answer:
The force needed to keep the puck sliding at constant velocity is 0N
Explanation:
Since the ice friction and air resistance are neglected, the force needed to keep the puck sliding at constant velocity is 0N.
The acceleration due to gravity (g) will be zero since there is no ice friction and air resistance taken into consideration, and therefore,
F = m*g = m*0 = 0N

Answer:
P=627.47W
Explanation:
To solve this problem we have to take into account, that the work done by the winch is
the force, at least must equal the gravitational force
with force the tension in the cable makes the winch go up.
The work done is
To calculate the power we need to know what is the time t. But first we have to compute the acceleration
The acceleration will be
and the time t
The power will be
HOPE THIS HELPS!!
Answer:
<h2>15 m</h2>
Explanation:
The distance covered can be found by using the formula
f is the force
w is the workdone
From the question we have
We have the final answer as
<h3>15 m</h3>
Hope this helps you
