Answer:
Option A
Air resistance
Explanation:
Despite the law of conservation of energy stating that energy can neither be created nor destroyed but can only be transformed from one state to the other, the process of transformation is not 100% efficient since some energy losses occur due to friction and air resistance. Therefore, when the final energy is slightly less than the original dor this case, it's due to energy loss due to air resistance.
Momentum formula - P=MV
P=MV
P= (3.5 kg)(6 m/s) - multiply
P= 21 kg x m/s to the east
Hope this helps
Answer:
Explanation:
The acceleration experimented while taking a curve is the centripetal acceleration 
. Since 
, we have that: 
They take the same curve, so we have: 
Which means: 
And finally we obtain:
