Answer:
1) Work is a measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement. 2) Work is calculated through joules. 3) It's possible to calculate work by multiplying the amount of force applied by the distance that the force is applied. If we know the amount of force the stick applies to the puck and the distance that the stick is applying the force to the puck, we can figure out the amount of work done.

Answer:
This is the formula
Explanation:
−(0.54 m/s)2
2(−1.67 m/s2)
so this is the step by taking the mean of the maximum value of friction with the minimum value you can get the average force of friction
It's basically asking for the acceleration. When an object is in free fall, the acceleration is just gravity. so in this case ∆v = 2.45 because it is the gravity on that planet.
Using momentum balance, we can say that the momentum
before the strike and after the strike are equal. Therefore:
m1 v1 + m2 v2 = m’ v’
However the door is not moving before the strike therefore
v2 = 0:
0.010 kg * 450 m/s + 0 = (7.010 kg) v’
<span>v’ = 0.64 m/s </span>
