Its actually A. I did the same question and A was the correct answer.
Answer:
915.69549 m
306.1968 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration = 3.25 m/s²
g = Acceleration due to gravity = 9.81 m/s²
Height is given by
Total distance the canister has to travel is 230+76.1968 = 306.1968 m
Time to reach the max height
Time taken to reach the ground is
Total time taken would be 3.9413+7.9 = 11.8413 seconds
The rocket is 685.69549+230 = 915.69549 m from the launchpad.
The total distance is 230+76.1968 = 306.1968 m
Answer:
Describe how the shape of the coast may influence an incoming wave. Explain using key terms such as reflection off the shape of the coast and reflection of incoming waves.

Answer:
<em>Maximum=70 m</em>
<em>Minimum=26 m</em>
Explanation:
<u>Vector Addition
</u>
Since vectors have magnitude and direction, adding them takes into consideration not only the magnitudes but also their respective directions. Two vectors can be totally collaborative, i.e., point to the same direction, or be totally opposite. In the first case, the magnitude of the sum is at maximum. Otherwise, it's at a minimum.
Thus, the maximum magnitude of the sum is 48+22 = 70 m and the minimum magnitude of the sum is 48-22= 26 m
