Hello can you retype this question so I can help you?
The answer is A. Only an object in motion has kinetic energy.
<span>Kickboxing is well known for being a calorie burning workout. It is estimated that a 30 minute session of kickboxing can equate to about 500 calories burned. The top two workouts for cardio kickboxing include the horizontal elbow striker which uses muscles in the abdomen, back, and oblique's. The second move is called the Thai knee strike which works the abdomen and upper legs.</span>
Answer:
c. 7.5 m/s south
Explanation:
<u>Given the following data;</u>
Velocity of duck = 10m/s due South
Velocity of wind = 2.5m/s
To find the resultant velocity;
Since we know that the duck is flying against a gust of wind, we would have to subtract the velocity of the gust of wind from that of the duck.
This ultimately implies that, the gust of wind (headwind) would decrease the resulting velocity of the duck because it approaches the duck from the front.
Resultant velocity, /V/ = 10 - 2.5
Resultant velocity, /V/ = 7.5m/s South.
<em>Therefore, the resultant velocity of the duck is 7.5m/s south. </em>
